I took his calculus 1 class and loved him! The material is just as hard as other calc classes but he was so helpful and if you spend time at his office hours an talk to him he will let you do extra credit and extend your webassign homework or give you extra tries when you need it. He also gives you a lot of info before the final so you are prepared

I took his class in the fall. He is a great prof and will actually help you get the the grade you want. He offers many extra credit opportunities. He is teaching a math course take him.

Professor Lee was awesome. He printed out notes for everyone to fill in. Also, the final was very reasonable as he understood the struggles of being a student. Great prof.

Dr. Lee really cares about students on an individual basis. His grading is not rough at all, he likes to give as much partial credit as possible. His office hours are flexible and will take time to speak to any of his students about all the assignments and tests. Homework is not very hard. Tests are basically straight from homework. Awesome Prof!

I didn't take Calc in high school, so before taking Math 151, I was really intimidated. However, Sang Lee is a good professor. He is very helpful and funny. He provides lecture notes that are very useful. Just make sure you study and pay attention in class.

I never went to class all semester, and passed with an A. The labs are very easy and you get a very long time to do them, the homework is pretty short and easy. I also skipped the lab classes because you can do everything from the lab from your dorm. The professor is really funny, but if you took high school cal, you won't need to go to class much.

Dr. Lee is a Great professor. You can even understand Him with his accent. Study the material and you will do good.

I was skeptical at first, but I really enjoyed taking his class. Get to know him and visit him during office hours with questions. I'm not a natural at math like others here, so I must work 3 times as much as others probably. I did well, and Dr. Lee was VERY accommodating. Wish I could take him for 152.

Even though this was his first time teaching Linear Algebra, he is AMAZING. Once you get over the slight accent, his lectures are very easy to follow. Study the notes, do the homework, and STUDY ANY REVIEWS GIVEN and you will be fine. Proofs can be difficult, but that's because proofs are difficult in general. Highly recommended.

He is my first professor here and ABSOLUTELY gave me the best calculus lectures I've ever had. Tho his print-outs are optional to print out, printing out and bring them to class will definitely help you participate more. He's good at making jokes during class, so classes won't be boring. Ask him if you have questions, that tells him you really care

Good professor spends a lot of time going over theorems but manages to still do homework examples. Tests are all hard because they are common exams so just go into this course expecting to fail and end up doing a little better than you thought

Dr. Lee is an exceptional professor. His lectures are filled with his insight and funny remarks here and there, and although the exams in 151 are all common, he does a good job of preparing his students. Would take again.

Professor Lee is the greatest professor I've had so far. Everyone gets the same amount of homework but he pushed back deadlines bc he was behind. All exams are the same but he gives you lots of tips. I LOVE going to his lectures and hearing his cute little jokes! He is VERY approachable and caring. I wish I could have him for 152. Take him!!!

He's a great professor who manages to make learning easy to bear with, although a downside is that there were times when the class lectures were behind on schedule. Other than that, he's great for any incoming MATH151 students!

Professor Lee has been by far my favorite teacher at A&M. He was great at explaining concepts and took the time to answer questions during lecture or outside of lecture. He even managed to make lecture entertaining with humor. He did well to prepare students for tests too. I would definitely recommend and hope I get to take him again someday.

Professor Lee was an amazing professor for a first time calculus student. He was always willing to help and explain during office hours if you didn't want to ask questions during lecture. However, due to how passionate he is about math he sometimes got caught up in his lectures and would fall behind. I wish i could take him again for Math152

He's a good prof, gives easy quizzes in recitation which is 10% of your grade. Pretty good lectures but if you've already taken Cal 1 you will be tempted to not go to lecture. Also gives an easy final.

You can tell he is really passionate about math and it shows in his lectures. He made lectures much less tedious with his enthusiasm. Homework is absolutely necessary to reach complete understanding. If you've already taken calc it should be really extremely easy.

Great professor. He's really passionate about math, and that made his lectures so much more interesting. No textbook, so going to class is important. Semi-long homework sets pretty much every week, but everything on the tests comes straight from the homework, so they're helpful. I made high A's on both tests solely from re-doing homework problems.

Dr Lee has been my favorite professor at A&M so far. He is really enthusiastic about math and he's charismatic which makes him a lot more approachable. He prints lecture notes for you to fill out during lecture, and tests are based off of homework assignments so it's easy to make an A on them. I highly recommend this professor.

Lee was a great professor. Went in depth, and understood what he was talking about. He really wants students to learn. He gives out note sheets in class and you just have to fill in the blanks.

Dr. Lee is a phenomenal professor who puts time into organizing his lectures in a way that's shows an easy example, notes the trend or theorem, then practices it with you. Plenty of in class quizzes, but they will save your grade and keep you engaged.

Sang Lee was an AMAZING professor. He is so far my favorite professor at A&M. He always makes lot of jokes and cute remarks. There are quizzes in recitation, but they are really easy. PICK SANG LEE! HE IS THE BEST!!!

He is a super hilarious professor who is always ready to answer questions no matter how stupid. He will sit down with you at office hours and go over test with you. He gives you advice on how to study better for the next test. Awesome guy. Really helps against those common exams.

Dr. Lee is one of the most personable professor's that I have had. He clearly cares for his students. He works through several problems in lecture to make sure we understand concepts and he posts an outline of his lecture before class which is very useful to follow along with.

My favorite professor this semester! He is very reasonable and caring, as well as hilarious. I loved this guy and he was a great professor. He posts his notes online and doesn't take attendance. I got a B+ but that's my fault for not trying hard enough. You won't regret taking Dr. Lee.

Lee is a super funny/chill guy, his accent is strong at first but after the first week you get used to it. I took BC calc in high school so I didn't have to study much besides before the tests, but I did spend a good amount of time working on the online hw. TA's help you with the hw so recitations are super helpful. Don't be afraid to ask questions

Sang Lee has been one of my favorite professors. He always makes jokes in lectures and explains the content very well and even gives out note sheets for you to fill in and posts the completed ones afterwards. Overall, if you take him and put in the work you will be very prepared for the common exams.

Amazing overall professor. Extremely nice and funny guy. He is able to explain the lecture at different speeds for different students. Quizzes were the absolute easiest things ever, and he prepared me well for the exams. HIGHLY recommend him.

I only have one specific complaint. When in lecture he tries to make every topic flow together which makes the entire class seem like one seamless point being made. This sounds good, but when in lecture it is hard to determine when he has changed focus and when you something new is being introduced. This makes it hard to follow along sometimes.

Sang Lee is an amazing professor. He tries to make his classes enjoyable and ensure that students understand everything they need to know before they take the brutal common exams. While he does move slower than most professors for Math 151, he fits everything in and emphasizes students understanding the why more than just the how. Highly recommend.

He was a great professor, simplified most topics and gave good advice for his tests. He made it fun and interesting to learn more.

Sang Lee's English is initially hard to understand, but once you adjust, he really is a great professor! He puts in jokes from time to time and allows you to print out fill in the blank notes. It might be tempting to skip class since there is no attendance, but going to class and doing the problems will help a LOT! Sometimes slow, but very thorough

Great professor, loves what he does, and always does his best to make a joke. The only negative I can think of is his examples didnt always match the difficulty of the questions on homework or tests.

Professor Lee is super nice and really cares about his students. If you have any questions he would encourage everyone to talk to him after class, or come to his office hours. He knows what he is talking about and loves to tell silly jokes throughout class. Don't buy the book though, I rarely used it.

Dr. Lee is one of the nicest, most down to earth person I've ever met, who happened to also be absolutely superb at teaching calculus. He uploads notes online, pre and post-lecture, so you can learn at your own pace if you care to. He's such a good guy, that he even came up to me at our rec and asked how I was doing in my studies. TAKE DR. LEE!

Absolutely loved Dr. Lee for this class. He is super good at explaining concepts and dumbing things down in a methodical manner for people to understand. Very clear with what he expects regarding homework, exam material, and during lecture. He's also pretty funny too, 10/10 would recommend.

He's a great professor. I'd definitely take him again if I had the chance. He gives fill in the blank notes and tells you what will be on the exams. I personally found this class to be extremely difficult since most of my time was taken up by other, more demanding courses. Be sure to dedicate enough time outside of class to learn the material.

Dr. Lee is the greatest professor I've had so far at A&M. His lectures make differential equations seem easy. He posts fill in the blank notes on ecampus for you to print out before each lecture and is very straightforward about the problems that will be on his exams. Make sure to study the note and homework problems for each exam.

People think of Diff EQ as being a very tough class but Dr. Lee does not make it seem so. He publishes great fill in the blank notes & will teach you everything you need to do well. The exams/final are hard but based on homework so not too difficult. Weekly homework that doesn't take too long and will help prep for exams. Really funny & just great.

Dr. Lee has notes with blanks that you print out and fill in during class, although the completed notes are always posted online later. The notes will get you a good grade on the test, and the tests will get you a good grade on the final. Dr. Lee is very enthusiastic about math and does not put you to sleep. Practice.

I loved Dr. Lee and his class. He simplified diffeq to an extreme. In my opinion, this was the easiest of all engineering math classes. Anything but an A shows a complete lack of effort on the student's part. Simply rework previous homeworks for the exams and it's very easy to do well; practice is the key. Very straightforward class!

Dr. Lee is a total stud! Not only was he the best math professor I have had at A&M, but the best overall professor I have had in my three years in college. His tests are based largely on the homework and notes so be sure to fill in the notes and study the homework. He does not give extra credit. 10/10 would recommend for DIffEQ. He makes it easy

Super funny and sweet guy, really easy class and gives a lot of partial credit on tests! Attendance isn't necessarily mandatory but he does give occasional unannounced quizzes (which are super easy) so you have to be there for those. Don't need to buy online textbook unless you want to use it for extra test review! Also posts all notes online!

Dr. Lee is a really caring and compassionate guy. His lectures are super helpful and he writes all of his notes on a white board, which makes it really easy to follow his logic throughout lecture. He simplifies DiffEq by only testing you on what's important and doesn't try to distract you with the bells and whistles.

Not the easiest to understand and doesn't have a great teaching style for 140. Material was super easy, yet he made it complicated. I would often question his way of explaining things and he didn't know how to work a calculator at the beginning. BUT pretty cool guy and tests easy & just like homework. Take him if you have previous math experience!

Prof Lee is great. strong accent but it isn't strong enough to be incomprehensible, you'll see you will like him more because of it. Tries to include the class a lot, very funny and a very nice guy. He doesn't take attendance but there are quizzes "weekly" (ended up not being every week) which he uses to make sure you came. Notes along w lecture.

I had a great experience with Prof. Lee! He is extremely straightforward with his lectures in class and makes it easy to understand concepts. Make sure to show up for class, though, because there are pop quizzes after some lectures. There is online homework, but it is nothing to fret over!

His accent is something that takes a little to get used to but does not affect your learning at all. He is a good professor and has a very structured class with notes for every class and online home works due the same night every week. The only negative thing is he does not make a review for the tests so you have to find outside resources.

TAKE THIS PROFESSOR. TRUST ME. Professor Lee provides all the notes so you can fill in during class, but if you miss class, you can still see the notes since he uploads them. He is VERY responsive to emails. He responded to mine in less than 10 minutes all the time. His office hours for this semester were MON-THURS for 2 HOURS EACH DAY.

Lectures are funny and easy to follow. He prints outlines but I never used them. As long as you show up, pay attention, and do homework you will not fail. His tests are examples from the note outlines, if you do miss class he posts filled notes online, but beware of skipping because he has pop quizzes (he ends up dropping lowest) FAV Professor ever

Dr. Lee is INCREDIBLE. I was dreading taking this class but he made the concepts so simple to understand. He also went over examples nearly identical to the homework and exams. He was the nicest professor whenever I had a question and was always willing to help. Take him!!!

Do the work and you'll be fine. Pay attention in class and the homework should be pretty easy. He is really sweet and makes funny jokes. His tests aren't tricky, just learn the homework and the class notes and you should get an A or a B. He always answers emails fast and is kind to students:)

Exams are very straight forward and similar to the homework. He let's you know exactly what to study before the test which is very helpful. Sometimes the notes are confusing, but they're not difficult to figure out. He responds to emails quickly and is helpful if you have a question.

Professor Lee is my FAVORITE professor at TAMU so far. His lectures are amazing and he prepares you for the exams very well. He truly cares about his students and getting less than A in his class shows complete lack of effort.

Dr. Lee is a solid choice for 308. Homework is graded very leniently, and he pretty much tells you what will be on the tests. Lectures can be confusing sometimes, but going through the homework usually helps.

Dr. Lee makes math fun with his personality. His ecampus work is phenomenal as everything is easy to find and clearly explained. Notes are easy to follow along and if you participate he'll say "Extra Credit!" and give you a whole point on your average. Tests aren't too bad if you work the homework and look at his solution guides. MUST TAKE!

Great professor who you will learn a lot from but also not have to stress about tests with. If you do the homework youll actually be fine on the test. An A is totally possible.

Material can be hard, but he makes it as simple to understand as possible. If you can do the homework, youll do just fine on the tests and in the class. Hands down the best math professor Ive ever had.

Lee does a great job of breaking down complicated concepts into more understandable pieces of information. He's an entertaining and clear lecturer. I took Calculus 1 in high school, but I retook it with Lee for the GPA boost, and even though I already had mastered most of the material, I still came to every lecture because frankly, I enjoyed them.

I took calculus in high school, so the class was easy, BUT he explained the concepts VERY well. He is very good at explaining tough calculus concepts, his lectures are prepared and keep you interested. He is pretty funny and he is good at answering your questions. 100% would take a class with him again. You will need to study- cuz its calculus

He is the sweetest man but it can be a little difficult to understand him at times. His tests are very easy if you do the homework. His final is the same questions from the tests. Homework is online and not bad either. Attendance isn't really mandatory if you have a good idea of Calculus

Dr. Lee is one of the best professors at Texas A&M. He is very caring and makes lectures interesting. He has a great method for notes and gives you all-time access. The very first moment I saw him I fell in love...

Dr. Lee is one of the best math 151 professors at Texas A&M. His lectures are understandable as well as hilarious since he cracks jokes here and there. I recommend doing the practice exams before every common exam as well as the cumulative final since they help majorly. I took calculus in high school so the class was not too hard. Take Dr. Lee!

Dr. Lee was overall a good professor for MATH 151. There were times in which some topics he discussed were confusing to understand, but I usually just utilize outside resources to fill in the gaps. He likes to include a few jokes here in there, and is a very caring person. Going to Week In Reviews help ALOT when it comes to exam prep!

Dr. Lee is hilarious and always wore a smile. His lectures were solid, with a heavy focus on the conceptual aspects of the material. He has an accent but it rarely interfered with my learning. Overall, he is incredibly passionate about math and is tremendous at teaching it!

Dr Lee is easily one of the nicest profs at A&M. He cares greatly about his students' success and will help you out if you ask. I got a B, but it is easy to get an A if you really pay attention in lecture and go to office hours. Do not do the web assign in class! It's tempting, but his lectures help a ton with the tests.

If you want to do well take as many practice tests as you can (i'd say at least three) before common exams. This man is a great prof, I got a B- because I didn't work hard enough for it. Show up to class, print out his notes, study a little, and you'll make an A

This is a math class so it will be a mid-difficulty class. There is a lot of HW,but not just his class it's all the math class and most of the Hw he gose over at the class.

One of the best math teachers I have had. Diff Eq was made to be scary but he made it easy. Clearly explains every thing and if you pay attention in class and fill out the notes and do the homeworks its honestly an easy A. Test aren't too hard either, since he tells you exactly what will be on it. Would recommend.

I took this course in the Fall of 2019. Dr. Lee is very effective at explaining difficult topics. He is very interested in the beauty of mathematics, and will oftentimes prepare interesting analogies between mathematical concepts and the real world. An easy A if you attend class, and have taken some form of Calculus 1 or AB before.

Sang Rae is an awesome prof! He keeps you awake during lecture with his sense of humor and making the content interesting. Easy in class quizzes. Homework is exactly like notes examples. Tests are exactly like the practice tests he sends out. He is very nice and wants everyone to succeed. 10/10 recommend!

Makes math308 a piece of cake. Gives the exact details in how to do his exam problems through homework, no fancy or overly difficult questions. EXTRA CREDIT!

Sang Rae Lee rocks! He is so nice and funny in class. He is also a genius lol. I would definitely recommend him and I hope I can get in one of his sections for some more classes. You do need to study though!

Actually incredible professor. Practice tests exactly like the real thing, super nice on grading, spends time going over the old material at the start of each class to remind you of what was going on. Highly recommend.

Much of notes/lecture is spent explaining theory you won't be tested over, but does good job of working and explaining example problems. Exams are no harder than homework and practice questions. Significant extra credit for correcting his mistakes

He is a really funny guy and you can tell he really enjoys the material he is teaching, which is impressive as this was a calculus class. The content was difficult, but he has good lectures and the TA was super helpful.

Great professor that really loves math and his job. He's a great professor with a bit of an accent, but it's easy to get used to and understand. I would take him for every math class if I could. His comedic relief always makes me smile. Such a wholesome man.

Dr. Lee is by far one of the greatest teachers I have ever had. He truly cares about the material he teaches and his students. He responds quickly to any email you send him. Also, he is one of the funniest teachers you will probably ever hear lecture, overall a great guy.

Very easy class. You are introduced to the program LaTeX, but it's not difficult at all. You have to transcribe 3 pages of a pre-existing mathematical paper in LaTeX, submit your resume, participate in a mock-interview (unless you already got a job or have actual interviews coming up) and write a term paper in LaTeX and give a presentation.

Dr. Lee is great! You can tell math gets him excited and he loves teaching it. SHOW UP TO LECTURES. His quizzes are basically an attendance check. They are 1 question and directly from the lecture. He also drops some quiz/HW grades. Also adds 1 point to your overall grade if you correct any typo throughout the semester.

Lectures are good, but he doesn't always understand questions, so TAs are helpful. The exams are extremely important to your final grade, but there's plenty of helpful study resources. Go to the MLC Week-in-Reviews!!

Dr. Lee is a great guy. He obviously cares a lot about the subject he teaches. He was a bit hard for me to understand at first with his accent, but once I was used to it, I found that he was funny and very approachable. Recitation helps clear up any further questions you have. He gives extra credit if you correct a mistake he makes during lecture.

He made his lectures and the math as fun as possible, I dont know why anyone would take anyone else but Professor Lee. If you do the work and all, the class should be an easy A.

Dr. Lee was a fabulous professor. He never fails to make you smile during his lectures due to his naturally appealing personality. If you truly care for the class he is teaching, it shouldn't be too difficult to find success. He responds to emails and gives extra credit if you point out an error he made in his notes! He really is a stand up guy!

Easiest math class I've taken and even through zoom it was really enjoyable. The exams aren't difficult but they make up a big portion of your grade (80%) so make sure you do well on the common exams and you can get a 70 on the exam and still get an A (haha I totally didn't do that XD). In all seriousness, great prof. with great lecture style.

Professor Lee is a great professor. He makes sure to go through the proofs before diving into the math topics, which I really appreciated. If you took CALC BC, there will not really be any outside work besides homework, quizzes, and tests. Overall, just a solid guy. Also. Has an excellent sense of humor.

Best Professor I've had. Take him and don't worry, hes the best in the business.

MATH 151 during Fall Semester. Prof Lee conducts great lectures that are primarily for notes. Quizzes consist of identical problems demonstrated in the lecture. Homework serves as great review. Python labs are run by your TA. Take multiple past exams as they serve as great review for each exam. Do the work assigned to be successful in this course!

Sang Rae Lee is one of my favorite profs at A&M. He is super funny and easy-going and explains concepts well. He's a pretty wacky guy who will always offer extra credit if you lend him a pen and he's just a great guy overall

Great choice for a professor. Offers tons of extra credit if you catch a mistake or ask a good question. I took calc in high school but I feel like even if I didn't I would have done well in his class because he's good at teaching. Jokes around in class.

Dr. Lee is one of my favorite profs at TAMU. I literally look forward to going to diff eq because of him and his great attitude towards math and life in general. Notes are neat, clear, and color coded to make things easy to read. He doesn't expect you to solve anything on a test he hasn't shown you before so practice homework and you are golden!

He is a real gem. He cares about students and understands if you can't do an assignment on time. His lectures are amazing and even though I already knew the material going into the class I still managed to learn so many new things. His final exam was pretty hard considering all other exams were common exams but if you do the hw you should be fine.

Great and Fair

Dr. Lee is the best math prof at TAMU. He's so organized and super clear in his teaching. For diff eq, you are mostly graded on two exams and a final, but preparing from past homework is sufficient to do well. He has such a great attitude, he literally can make your day so much better. A real gem and 100% worth trying to get into his class.

all the reviews already mention how great of a teacher he is, so I just wanted to point out that he's also a genuinely amazing person. his kid walked into a lecture recording accidentally and the way he responded was just so wholesome!

He makes diff eq so much easier and interesting to learn. The notes are easy to understand and the homework and quizzes closely follow. The exams are all based off of hw questions. This was the easiest math class that I have taken at TAMU and I wish I had him for my other previous math courses. A really nice, cool guy with a great personality.

Dr. Lee is a great lecturer and makes the class more lively with his personality. He encourages participation in the form of extra credit! If you have trouble submitting homework/exam work, email him; he is very understanding and automagically ensures an accurate grade. Exams are just like homework. He makes abstract concepts palpable in Diff Eq!

I took Professor Lee for 151 and 308. He explains concepts from the ground up so that there is no confusion. I really respect him for this, since it is invaluable. His tests can be hard sometimes, but worth the trade-off. Wholesome professor I've never met someone this happy to teach math. Led me to minor in math.

Dr. Sang Rae Lee is really kind and caring to students. He gives extra credit for participation. He is not the best at answering questions at times, but only because he does not understand what you are asking. He goes into theory and explains from a solid foundation that he builds. I definitely enjoy his class and Dr. Lee is funny.

I took AP Calc in high school, so I already knew all of the material. However, it was still an awesome class! The prof gives extra credit if you correct an error, and thoroughly prepares you with lectures.

I took calculus in high school, but Dr. Lee was still very engaging and taught me some more in-depth theory. He was funny, and has a great bonus point system that is helpful at the end of the semester. The tests are worth a large proportion of the overall grade, but he will replace your lowest exam grade with your final, if you do better.

Had him this year he was so nice and funny ! He did go fast at times to get the knowledge in but he would stop anytime someone had a question. The hw and practice exams were very good material to help study for the exams which were about 75% of the grade

Great teacher is super personable and if you have a question he tries his best to answer it. The only thing is that his notes are confusing to follow when referencing them outside of class. Otherwise, solid choice.

Dr. Lee is super funny and makes his classes nice to go to. Always do your work outside the class because your whole grade in any 151 class is based off of the common exams that are 20% of your grade each.

He is hilarious and decent. The lecture he gave us not just examples but the context, the name of the problem have to be done. He did not use much technology, but it did not make a big deal. I like him.

MATH 151 itself is complicated, however, Dr. Lee helped get me through it. As a non-ENGR, I would get lost in his lectures at times but I consistently went to office hours and he helped walk me through the material. MATH 151 has 3 common exams with a professor-specific final. Weekly WebAssign homework and online quizzes. He is hilarious and kind!

This man cares about teaching diff eq, and his students, he took a difficult subject and has taught it incredibly well. Really good organization, I knew what I was doing the entire time. If you can take him, take him.

Dr. S.R Lee makes differential equations so clear and simple because he has such a deep understanding. He hardly makes any mistakes during lecture but if he does, you can correct him to get extra credit. The extra credit will push you over the edge if you are at a borderline grade. Dr. S.R Lee is charismatic and awesome!

great professor I struggled with math 151,152, and 251 but for some reason I had such a breeze in diff eq with dr lee. I would recommend him

Prof. Lee taught 308 well, and delivered the material at a very easy to follow pace. Basically the whole class was easy, and he made it easy to nail the quizzes and homework. The final exam was difficult however, so make sure you are studying thoroughly because you will lack the reference material that made the homework and quizzes easy.

He is really caring and respect to his students. He made things clear and easy to follow. Recommended!!

The 2 midterms were pretty similar to the HW and our class average was high, but the final was a lot harder. HW was not too bad, and not all of the questions are graded. The HW and quizzes are 30% of your grade, and this should help with your grade. In this class, we focused on solving example problems instead of going over theories.

Very funny and charismatic professor. Notes outline the material well and homework is consistent with the lectures. The final was unusually difficult compared to the rest of the class, and the average definitely reflected that. Brought me down a whole letter grade, so be very prepared for that. But otherwise, no complaints. Great prof for 308.

I have no idea why Professor Lee doesn't have 5 stars. Dr. Lee is in my top 2 of best professors I have ever taken at A&M. He makes diff eq so easy to understand and gets straight to the point with clear, concise lectures. He is extremely understanding and cares for his students well. If you understand the homeworks, you will do fine on the test.

Professor Lee is a godsend for diff eq. Extremely organized notes that were fill in the blank. Emphasized different problem types rather than focusing on complex theory. You'll be fine on the exams if you understand the homeworks. Final exam was a little tougher than expected. Overall one of the nicest and most caring profs I've had.

Very enthusiastic about math and gives great lectures. He occasionally gave an extra credit point to people's final average if they participated/asked questions in class. Tests were pretty fair overall, as long as you do multiple past common exams before each one you'll be completely fine. He was very caring and accessible outside of class.

Very passionate and caring. He tries very hard to keep his lectures interesting and in general cares about students. Always has a smile on his face, and attending his lecture feels so wholesome. He is good at explaining the material. Exams are similar to HW questions. attend lectures and do the assigned work and you will get an A.

The most passionate prof I've ever had. Tries to make lectures fun, and also gives small extra credit for finding typos in his notes. One HW and a super easy online quiz per week. Test questions are straight from homeworks so do those and you'll be fine. Definitely recommend.

Very caring and sweet professor! Lectures are helpful & he posts recordings as well. Accessible outside of class via email & office hours. Take Sang if you can, you won't regret it :) As long as you do your homework and study before exams you will do fine.

I was nervous about this geometry class, as this was never my favorite topic. This professor is great though! He uses guided notes during lectures and the homework is very easy to do after the lectures. My only concern was the test was very heavily weighted on one week's topics that were rather difficult. The project is useful for final oral exam.

This dude is the GOAT. He's really funny and a great teacher. People say MATH 152 is the hardest math class at A&M, but Sang Lee made it seem rather easy. Homework is somewhat tedious but not overwhelming. Exams are pretty easy. Make sure to go to lectures and you'll be perfectly fine.

Dr. Lee is an amazing professor, who really cares about what he is teaching. Math 152 is a pretty hard subject, but Dr. Lee made this course concise and easy to follow. His lectures are funny and intuitive, and his personality really alleviates the difficulties of this course. Take Dr. Lee!!

Great prof for 152, I was worried because this is a notoriously hard class but I found it easy to follow with Prof Lee. Honestly felt easier than 151 at times because the whole class is pretty much just integration and series. LOVED THE ONLINE QUIZZES. Very open to student questions and is funny. Showed lots of graphs on desmos which was helpful.

He is so wonderful! Very nice to talk to 1on1, this year was his first time teaching Math152 and he made it so easy to understand and sometimes even fun! I HIGHLY recommend this professor for this course! Quizzes were online and very easy (however you must attend class to get the quiz code).

The lectures should be attended because the curriculum for this class is different than what is taught with other resources like YouTube, a lot of times you actually need to know less for the class. Tests make up 80% of your grade with 20% other material like HW and quizzes. Do HW and past common exams to pass, this is the only way.

Quite enthusiastic about the subject. For the most part all lectures are helpful. However, when there are 2-3 core lectures that left people confused. The MLC taught it better. Apart from this great professor, very friendly, hilarious. He made 152 quite easy and is probably the best math 152 prof out there. Study for exams from past common exams.

MATH-152 is known to be difficult at TAMU and I was scared going into it as a 1st semester freshman that had skipped 151. However, Dr. Lee made lectures fun and taught the material well. He even uploaded class notes to Canvas. The final was also very reasonable! If you go to lectures, complete the homeworks, and grind past exams, you will get an A.

Very nice professor. Great at responding to emails and students' concerns. The class is definitely doable as long as you pay attention to what's going on, do everything on time, and grind for common exams. It is very possible to do well and get every question right on the exam as long as you grind enough common exams (5+).

First time teaching 152 so it was a little rough. Made lectures really easy to understand and follow. Notes were easy to follow and access if missed class. Online quizzes were easy. Almost didn't pass but was really understanding of how close I was. Really kind and wants students to learn

Good math prof, makes sure all students understand the material before moving on and tries to be clear about everything. Quizzes were online and open note, homework was fine but the course was very exam heavy so make sure to study. Final was really hard for someone who got consistent B's on the exam... be careful.

I failed this class before with different prof, but I'm getting A now. He explains every single details, so if you don't remember pre-cal, it doesn't matter. The only thing is that he gives you sudden quiz through online, but is super easy. The answer is already on the lecture note. Definitely take him!! He's the best prof I met here!!

The goat.

Lee was a great prof and made lectures very entertaining with interesting humor added. His lectures would place emphasis on actually deriving the formulas we'd be using which would make understanding them easier. Math labs suck so make sure you get a good group. Practice every single common exam.

Great professor. He was great at explaining topics and gave plenty of example problems to help with understanding. He makes you attend class to get the password for his attendance quizzes which aren't difficult. He has entertaining lectures and is good about answering any questions you have. Practice the past commons exams and you will do fine.

If you have the chance to take Prof Lee, DO IT! He is amazing at making lectures energetic and fun, and clearly cares about student learning. The final is quite difficult, but the rest of the class is definitely manageable, so don't let your grade slip early. He is probably my favorite professor that I've ever had. 12/10.

I had Sang Rae Lee for MATH151 and he was really good at teaching the material so I was really excited to have him for MATH308. Personally, I believe he was pretty efficient and clear when it came to teaching for this class and he makes the exam content based on things you've seen before so that was nice.

Professor Lee was an amazing differential equations professor. He does a great job teaching the material and answering questions in lecture. His exams weren't too difficult and if you study the homework you should do fine on them. Professor Lee was one of the best professors I've ever had and I would absolutely recommend taking him!

I loved Sang Lee, he was an amazing lecturer and thoroughly explained every topic. There were pop quizzes that were online, however, they had passwords he gave in class. Tests were like practice exams and homework, Only critique is that I had an A all year then the final brought me down to a B, compared to the other two exams it was much harder,

His lectures were easy to follow, and he always answered questions very thoroughly. He definitely cares about his students and explains concepts really well.

Literally the best professor ever. Funny guy, great lectures, cares about his students.

Absolute legend of a prof. Taught the course pretty well, tests were basically carbon copies of homework and everything else was free points. Didn't really go too in depth so I didn't learn all that much but the class was super chill.

Enjoyable lectures and easy-to-follow notes. The first exam was a little long and he compensated for that and made the second one more reasonable. You really can't go wrong with him, he makes the course extremely doable as long as you keep up.

Probably the best math professor I've had. Tries his best to make his students laugh and tries to explain material in the best way so everyone can understand. Take him if you can.

Professor Lee is the best! He is so incredibly kind and genuinely cares about your learning! He gives great lectures and the tests are not difficult if you can do the lecture problems. Could not recommend him more!

Cares about students and truly wants them to do well. Good notes that are easy to follow and make the concepts intuitive. Definitely would recommend taking 251 with him if you get the chance.

Professor Lee is an amazing professor who is easy to learn from. He gives you everything needed to pass and excel in his class with his amazing notes, challenging homework, and quizzes. While attendance is not mandatory and notes are posted on Canvas, showing up to class would be for your good in knowing what you are doing for the quizzes and tests

Take Dr. Lee. He is extremely nice, and gives good lectures. He outlines the exam content in a very clear way. Attendance is not mandatory, but it is helpful to go. Overall great professor, take him if you can.

Fantastic professor. The class is fairly reasonable, but the final is a bit more difficult. If you attend lecture, do the homework, and do the practice tests, you'll do fine.

He is great! While I did find it hard sometimes to understand him (might be a me thing) he is energetic and brings an infectious and fun energy. Lectures not required if you took calc 1 in highschool but he does give extra credit if you help him, overall he makes the class easy and an overall enjoyable experience, 100% would take again.

Professor Lee is great - his lectures are engaging and he genuinely cares about student learning. While attendance isn't mandatory, going to class helps you excel. unstuck study was a game-changer for my study prep and practice.

Prof Lee is a very good lecturer, his notes are very clear and he puts them on canvas. He is a very sweet and quirky person when you get to know him! It is very apparent that he loves math and he likes sharing that with his students. The class is test heavy but that is just MATH 151 in general. Go to his office hours it helps a lot!!

Always wearing a smile. Feels like he's happy to be there. Sometimes, he'll go slow to emphasize a point and then speed through the next bit, but generally has a decent pace. Posts lecture notes in Canvas if you need them. Great guy!

Professor Lee is very good at explaining math concepts and helping students understand them. The class itself is still hard, but he does the best he can at teaching the students and he is very meticulous and detailed when it comes to his notes/lectures.

Professor Lee is the goat of the math department. His lectures are very clear and concise, and his passion for the subject is evident. The class itself has about two homeworks per week, each about 8-12 questions, but they are online and you get four attempts per question.

Professor Lee is a great lecturer and is easily accessible outside of class. The majority of the grade for Math 151 comes from common exams and the final. He frequently jokes around in lectures, making the class enjoyable. I would definitely take Professor Lee again!

Professor Lee is a very funny professor who also teaches really well. He makes every topic simple and he tries to incorporate humor with his lectures too. He is amazing and a great teacher and really helped me understand math easier. Take him if you can he will make your life so much easier.

funny lectures and would frequently let you know which question in lecture was going to be in the coming weeks recitation. bro is the goat and is very approachable. celebrate when u find out he is your professor bc the semester will be good. make sure you study and PRACTICE ALL COMMON EXAMS AND DO HOMEWORK.

Very humorous. Explained things very nicely and clearly. I was never bored in his lectures. He always let us know what was to be expected of us in the next few weeks. The notes that he uploads to Canvas are fairly easy to follow and understand. Would recommend.

Dr. Lee is amazing! He teaches the material very well and he is very funny. He cares very much about his students and how they do in his class. Take this class if you can!

Dr. Lee is for one a great lecturer, and has very detailed notes, but most of all he is hilarious. The class itself isn't too bad if you study his notes, past exams for test. I also went to the WIRs (I never took calc in HS). This year they made the common exams slightly harder because our averages were so high and his final was very difficult.

Dr. Lee is an great lecturer. He makes want are hard to learn concepts easy to understand for people learning the material for the first time. There are quizzes and homework, but they are worth relatively little to your grade. 4 tests make up 80% of the grade so study. My grade currently depends on the outcome of the final bc i slacked off for one

No pop quizzes, attendance is optional, lectures are great. Reviews that claim he is difficult to understand aren't really listening. He takes questions during the lecture and will re-explain if you don't understand. Pay attention and you'll be fine. Sit front row if you want extra help. Exam heavy grading, but thats department.

Decent amount of homework and tests made 80% of your grade. Final replaced lowest exam grade. Lectures were a bit boring, especially since he would walk in and dim the lights every class... but if you didn't fall asleep, he provides you with all the knowledge that you need to be successful on the exams. With studying, getting an A wasn't too hard.

Dr Lee is phenomenal and hilarious! Lectures were pretty easy to follow and he offers extra credit if you correct him or ask good questions. Tests are worth 80% of your grade so take them seriously, but also the final replaces your worst exam. Be careful on exam's written responses as you are graded not only on your answer, but your work as well.

Didn't require attendance in fall 24 but I still showed up because he is such a great lecturer. Very funny. Provided very well organized skeleton notes which he filled out in class which was extremely helpful for me. Goes over past common exam questions that students pick before exams. In short, THE GOAT.

Dr. Lee was always great. His lectures were funny and easy to understand, and his exams were very reasonable. Attendance wasn't ever really mandatory, but there were weekly quizzes in recitation that had to be taken in person.

Proffesor Lee was VERY KIND and undertsanding. If you need something do not be afraid to ask. His lectures are helpful and he posts his notes. I reccomend working through the practice questions prior to taking the exam, it will pay off.

Math 151 is a difficult class. However, Dr. Lee makes it very easy to understand and grasp the concepts. His lectures are clear, and he answers any questions that you may have. The common exams for this class suck, but the practice problems are helpful, so definitely do those. The final, which he writes was easier than the common exams. Take Lee!

By far the best math teacher I have had. It was a breath of fresh air after my Calc BC teacher in high school. He is very passionate about math and makes you want to learn. He was very nice about answering questions, didn't get frustrated, and didn't make you feel bad about asking. You can tell he cares about his students. 10/10 would recommend.

Professor Lee is a fun person and teaches interactive lectures. He's very helpful when it comes to doubts over the subject and very clearly enjoys teaching the subject.

Professor Lee was a fantastic professor. His class was very organized, he thoroughly explained every concept, and his notes were easy to follow. He was also very fair with his due dates and grading policies and very clear with his expectations of us. He is also just extremely upbeat and funny, so it's enjoyable to go to lectures.

Sang Rae Lee is da goat

Sang Lee was excellent! Attend class, do homework, and work out all the practice exams and you'll get an A without difficulty.

The lectures were great, and the guided notes were really useful in doing the homework / studying for exams. I just found the subject difficult and made a lot of stupid mistakes on my exams that added up quickly, but that's just how it is sometimes. He replaces your lowest midterm with the final which is great!

He made the class very fun. He was always very kind and made jokes in class. He also gave extra credit to students who caught typos in his lectures. My first encounter with him was on the first day of class where he held the door open for me as we walked in ILCB and he gave me a big smile. He is the GOAT and I did not hesitate to take him again.

I had never taken Cal 3 and skipped Cal 2. He makes the class really fun and the material easy to understand. He is super funny and jokes around with you. He shows you cool math concepts that you can "show to your grandma". He is amazing if you have the opportunity I would take him. I am taking him next semester for Diff Eq and would every time.

Professor Lee is the best professor I've had so far at A&M. He is very caring for his students and is always in a great mood for every lecture. His teaching is great, and the notes that were provided for each lecture helped to make this class easier than it might normally be. I would 100% recommend Professor Lee for any math course that he teaches.

In my opinion calc 3 was worse than calc 2 but Professor Lee was a great lecturer and was quite entertaining. He was very quick to respond to emails. All the quizzes were take home and he would drop the 2 lowest and drop a few hw's. Lot of his exam questions came from the hw's or were similar. However he doesn't curve and no extra credits either.

Loved the energy that he taught with. Entertaining during lectures, which you must attend if you plan to do well on the exams. The content (especially chapter 16) builds quickly. His exams werent super hard, but he made them way too long for a 50 minute class and even acknowledged it. The take home quizzes are on random days so watch out for that.

Sang Lee is an incredible professor for this class. He takes his time to explain topics well, answers all questions, makes some good jokes, and overall, I can't imagine anyone better. Exams are largely based off homework and notes (not bad, but Final exam content is much more difficult - do well early). Take home quizzes. No mandatory attendance.

Prof Lee brought an upbeat vibe to all his lectures and made jokes, and he also provided useful fill-in notes and helped students who had questions. The exams are challenging, so I recommend studying a few days in advance and taking the practice exam he provides. The final is a step up from the midterms, so prepare extra well!

Sang Lee made class very enjoyable and a pleasure to attend. He teaches very well and lets the students know everything that is expected of them. He provides practice exams that are very helpful for you to achieve the grade you want. By far the best math professor i've ever taken and I wish him well.

He is a good lecturer; the tests are very similar to the homework. Quizzes are only announced in class, so check Gradescope often if you are not going.

One of the best math lecturers I've ever had. I took MATH 308 during a fast-paced 5-week summer session, and despite the heavy workload, he made each lecture engaging and clear. He taught with such enthusiasm and clarity that it was hard not to enjoy learning the new material with him. Highly recommend!

Professor Lee is an amazing Prof and I would highly recommend. I took him for Calc 3 and his lectures were clear and informative, his notes were good, and his tests are fair. You will definitely have to study and do homework on time but if you show up to class and do the work he is very doable.

I have Professor Lee for my MATH152 course. He is incredibly passionate about teaching and makes his lectures very engaging and easy to learn from. He responds quickly to emails and in general is easy to reach when help is needed.

Took 251 with him last semester and am now back taking 308. I created a Rate My Professor Account just to write this review. Dr. Lee is not only the best math teacher I've ever had but also the best teacher I've had period. His lectures are deep and engaging and keep you entertained with humor sprinkled throughout. He successfully makes math fun.

Absolute goat. He knows how to dumb down calc 2 to an insane degree and is an extremely fair grader on FRQs. So long as you are not playing clash royale in class, this should be your easiest A in college.

Dr. Lee is probably the best option for 308. Exam is exactly like the homework and there are no surprises. One HW a week, pop quizzes used as attendance checks (we only had 4), and the final exam was also very fair. Straight forward and amazing professor, makes class fun with good humor. Extra credit if you catch his mistake too. Just study the hw.

He's actually the goat. Take him if you can.
