This class has consumed my life. The tough homework he assigns is collected weekly. Expect to spend two hours each day doing it. Tests are difficult as well. Work hard in his class, and it won't necessarily pay off, unfortunately. This is coming from someone who had an A in math 110A.

He is an EXCELLENT teacher I have ever met. take his class you will understand MATH 110A/B/C clearly. trust me! I got A in 110A, also this semester I will get A in 110B . after that, your will feel your math stronger than before.

He is the best teacher city college has to offer. Very clear and Very Thorough; i will admit, he is very very tough, but one of the best damn math teachers ever!! he will help you and encourage you to stick with it even when you're doin poorly, and he will motivate you. very good teacher

His class give me confidence, I like his lecture and all of his handouts, they are very helpful and worth to keep. After u take his math 110B class, his gives u confidence.and his special tech. on math is very thoughtful. RATE 100% worth to take it.

easy class,this teacher is thoughtful. this semester I got A in final test!!

Good teacher, I got an A in his class. A lot of homework to do it, but u can get A in test.

This is a great teacher who really cares about his students and really knows his subject matter. He is very good at explaining things from the beginning (before everyone is confused!). He sets the students up for success. Can he teach all of my classes?

Can't love him more. I admit he's a bit hard but he absolutely prepares you for future math challenges. I took the whole calculus series with him. It's not easy but I enjoyed his class. Very clear both in lecture and his homework solutions. If u are serious about math take him.

He is the best teacher I've had in CCSF. He knows the material very well, and explains very clearly. Plus, he's always patient, helpful and concerned about students' learning. Homeworks and exams are pretty challenging, but they help you learn alot. I highly recommend to take math classes with him.

his class is quite difficult but i did manage to get an A, he is quite clear on what he is saying, but if you do not understand the concepts, you might have some trouble, take him if you have high interests in math

It's not easy, but when you are done you will really know your stuff. Prepares you for future classes and he seems to have a lot of friends in the industry (engineering) so he while he teaches he also prepares you for the future.

Mr Lee loves math and is excellent at teaching it. He is increadibly smart, nice and clear in his lectures. When students have questions he's patient and understanding. I would recomend him to anyone. He gives alot of homework, but it comes with the teritory!

Good if you are going on to take calculus

Very helpful, clarity, give very careful steps. He is hard, but you learn alot from him.

he's very clear and loves what he teaches. you'll definitely learn a lot. but this class is not recommended to procrastinators, like myself. once you lag behind, it's very hard to catch up. plus he does not allow cheat sheets on exams so you'll have to memorize all the formulas.

This class was the hardest class ive ever took at city college and ive been attending for 3 years. He is crystal clear but doesnt give you enough homework. On the first the highest grade in the class was a 84%. I had to drop it. If you need the class to graduate i wouldnt recommend him. he didnt use the book much either like they said.

He's a wonderful teacher. He's very organized,understandable and useful. Even though his class is pretty hard, you can still pass the class by just attending the class, listening careful, doing your homework. Good luck!!

Extremely nice guy that is willing to help you out. He's really hard, Mr. Lee is brillant and sometimes loses sight of the level of his students. I recomend taking him only if your really ready to work for your grade.

Mr. Lee is a nice guy, tries to help you with the best of his ability, but most of all you have to do the effort. There are two numbers you should know: less than 50 is an "F" and more than 90 is "A", in between depends on class performance. If you get a 60% on a test, that can be a "C" or better. I dont recommend him if you're not willing to try.

Although Precalculus is quite a tough subject, Mr. Lee is a fair teacher. He allows a take-home portion of most of his exams. Homework is optional, but necessary for comprehending material. Overall a nice, organized teacher who wants his students to succeed.

Correction: Mr Lee is polite and has good handwriting. He is challenging and fair. If you don't want to study or do homework, you will do poorly. If you want to apply yourself, you will learn not just the how of pre-calculus, but the why of it as well.

Very good teacher. Makes the material very clear on how it is supposed to be done, and points out common mistakes from earlier classes. Hands out notes for everything he teaches and goes over all examples in class. Sometimes lets the class out late, though. Highly recommend to anyone with a math or science major.

Extremely huge workload but quite fair for science major students. Good teacher and good teaching, though I am having a hard time to pass the class but I realize that is really my problem. Preview the material far ahead of the semester begins!

Mr. Lee is a great teacher! Very thorough, knowledgeable, and genuinely wants his students to be fully prepared for calculus. I'm a slacker (and bad at math) so I totally flunked this class, but I'm fully prepared to take his class again and really try my best. He's probably the best math teacher at City and I'm really appreciative of that.

He is difficult for sure, but his lecture, clarity, and note are the best of the difficult math teachers. Math 130 is just a hell no matter who teach it.

He is very knowledgeable, polite, and has high expectations of his students. If you put the time and effort into completing the homework and practice tests, he will be there to help you every step of the way. A bit heavy on the theory side, less on the practical side.

Mr. Lee is the best teacher ever! He lives to teach and makes sure we understand everything he's trying to convey. He gets down to our level of our understanding so that we will be able to comprehend ridiculously complicated concept. It works. He makes math fun and interesting, like it's a game or a mystery to be solved.

I'm UC Berkeley student who took his class 1 year ago. There is just one thing I can tell about his class. His class is as hard as UCB classes, period.

Mr. Lee is the best math teacher I ever had at CCSF. He hands out notes that are awesome, I never read the textbooks. You do need the books for homework though. I'm now taking upper div linear algebra, and it is a breeze thanks to what Mr. Lee taught me. Be prepared to WORK HARD to pass.

I took Mr. Lee's class last semester and found that he's one of the most competent teacher I've ever had in my years at CCSF. He teaches in a very systematic way, and guides you in solving difficult math problems step by step. It is not guarantee that you'll get an A since everyone's potential is different. But you'll learn the most if you take him

On recent exam median score was 30/50. If you take this class you WILL learn the subject and you WILL work HARD, you will probably also end up with a low grade on your transcript! Lots of HW assigned, only some is graded: 95% of the work might = 50% for your grade! Grade given does not reflect time or understanding of subject which is BS!

3 words to describe him he is awesome . Btw, for people who are not getting grades you want, maybe you all need to spend more time on your hw instead of commenting on this website to get better grades. One more time, Mr.Lee, you're awesome!!!!!!!!!!!!

I have had a lot of math classes at CCSF,but Mr.Lee is the only prof who actually prepared me for the university-level workload and teacher expectations.He was also helpful during office hours and he changed his grading system to help some struggling students.Take him if you are ready for some challenge and want to get some serious math knowledge

If you are just looking to learn advanced algebra concepts before going to calculus, take someone else. The class is number theory and philosophy put together. If that's your thing, be my guest. Only other people who have taken his class can help you if you are stuck. He doesn't use the book much, but he is happy to answer questions. Go to class.

If you really want to learn,take his class.lots of hw,turn in on Tue,give practise test before test,offer office hours.The tsets are Not hard as long as you do the hw, practice and pay attention to his class.Take his class,prepare to work hard. A very goog instructor.GO and TAKE IT.

Prof Lee teaches extremely well. He preaches concepts and will help you learn math. He grades very hard on required homework but easy grading on tests. Tests are also easy if you do homework. LOTS of homework. Overall great class, very helpful & flexible office hours

He is a good psychotherapist!

Mr.Lee, you rule

I believe, he is the only professor on campus who is actually preparing his student to the world of university-level mathematics and workload in general.

I Love Mr.Lee. He is clever with his math jokes every now and then. He is very clear and precise. His handwriting and organization is very neat. He passes out a practice test most of the time, which is very similar to the real test. Probably one of the best math teachers in CCSF.

Professor Lee is the best math instructor in calculus I have ever encountered. His passion for the subject is obvious. His homework is very difficult and time-consuming, but if you put in the time to understand them, you will do well on his exams. He is very approachable and really cares about his students. Go to his office hours if you need help.

Professor Lee is a great teacher: very organized, intelligent, helpful and funny at times. However, his class is VERY hard to pass with an A or B. He only wants his students to use his methods of problem solving. He wouldn't give you points for getting the right answer by using your own method. After hoooours spent with tutors I barely got a B.

Lee is the best Math teacher I've ever had. If you need advanced math for your major, take him as much as possible. If you're looking for an easy A to fulfill an algebra requirement, TAKE SOMEONE ELSE. If you're ready to work hard, he can have an incredibly positive impact on your mathematical ability and confidence.

Mr. Lee is one of the best teachers I've EVER had! He is organized,thorough,well prepared & passionate about the class. The HW load is not light but doable. He prepared me well for my 4-year university! The exams are not that hard if you do the HW & do them over again before exams. His exam problems tend to be similar to the HW ones that he GRADED.

it is best to sit near the front of the class. can barely hear him talk and writing little bit hard to read (his "y" looks like x sometimes) and writes very light, easy not really, test pretty tough if you dont study the notes

i like him so much. he is such a great great teacher. his class is not easy and hw is time consuming, but he never trick his students. also he is really helpful. his care about his students. if you study hard, you will finish his class with good grade and fulfillment.

Knows what he's doing. Withdrew due to my lack of preparation, however with consistent communication, I'm definite I would have stayed. Stay on top of HW and the exams will flow easily through. Will take him again.

You'll get a thorough understanding of Calculus. He all about concept and making sure you know what you are doing. "Do math with a purpose" is his motto. That and "why?". He gives you HIS notes and HIS problems. (As an aside, many tutors aren't able to do his problems) You'll work hard for an A, AND you will have confidence using Calculus!

I must agree with the previous reviewer. The instructor stresses concept in dialogue but in practice takes a mind-numbingly formulaic approach. This pretension results in a very boring and tedious experience. I ended up dropping the class and am now studying "A Course in Pure Mathematics" by Hardy, a far more engaging treatment of the subject.

Lee is one of those rare, life-changing teachers that you never forget. Lectures are funny, clear, and inspirational. Provides his own notes, 2 practice tests, and detailed solutions to ALL hwtests. People who put him down are just lazy or cocky. If you pay close attention, you will seriously learn more about math, life, and yourself than therapy.

His class is tough, you need to study hard and then study again. Any math class worth its salt should be like that. Going to class is worth it when taking his classes. If your head isn't burning after a class then you aren't learning.

Professor Lee will provide the feedback you need to genuinely understand Calculus. This man's bane is rote memorization and a formulaic approach, so if you've used these as crutches up to now he will force you to rely solely on your legs. He assiduously grades homework; any flaw in your approach will be found and eliminated. Highly recommended.

Best professor I have ever had. If you want go into science or engineering, I would recommend to take him. We were exposed to proves in 110B which was different than calculation. Problem sets are not easy, but doable. His teaches in a university level and gives very clear supplementary notes.

This was most likely the hardest math class that I ever took. I didn't passed his class but If I ever got a chance to take his class again I would. I hate to admit this but Mr. Lee has more math knowledge then me.

I took both Professor Lee's 110A and 110B classes. The instruction was really great. He walks you through the material; hence, you learn something every time. I am glad I took his classes. He is a very good instructor. I received an A in both classes. Now, I tutor my brother who is in the 8th grade taking pre-calculus. See ya!

Last Fall I didn't passed Calc 3 but then I retook Calc 3 with the same teacher and I beat Calc 3 and now I am ready for my next challenge. After taking Mr. Lee, I feel like my math has gotten a lot better and I also learn a lot. Overall, I think Mr. Lee is a good teacher and I hate to admit this but Mr. Lee has more math knowledge then me.

Mr. Lee was a difficult teacher. His tests were very hard and the homework will take hours to finish.

Me. Lee is really nice professor and he takes his work very serious. His lecture is well organized and clear. Grading Homework is not a big problem for me because it pushes me to catch up with the class. If your major is strongly related to math and you want to learn morehe would a good choice for you

Prof. Lee is a wonderful teacher. He comes to class every single day, even he lost his voice. His feedback of homework is clear and helpful. He also does homework every single time with us and put it in a beautiful blue folder to help us to check it out. This is very helpful for us. I have learned a lot from him, and Illtake his class this fall.

Prof. Lee clectures clearly and methodically in his class. He shows us the best way to solve out problems, and he discusses the details clearly. He helps students to build the real mathematical thinking for future, not only passing the class. He is the best professor in ccsf. I enjoy his class and learn a lot from him. Ill take his class again.

Lee is a great professor. It is unfair for Lee for some peers who are not responsible for themselves to say somethings untrue here to hurt him. They dont want do hw then blame there is too much hw. They are spoiled like an infant that they should have A with doing nothing. If not, they say you are too difficult. They are in playground not college.

Prof. Lee's class was my first college level math class. Yes, students say his class is difficult and rigorous. So people avoid taking his class. Obviously, I am not good at math, but I challenged myself, spent many hours at the math lab. Result? Passed with A+, learned invaluable and foundational knowledge about Calculus. Thank you Professor Lee

Prof. Lee is a wonderful teacher. He comes to class prepared and his lecture are very clear. Also he gives a lot of feedback on his homework so you have a lot of time in improvement. I have learned a lot from Mr. Lee both in class and outside of class. I am statistics major and he gave me advice with regrading statistics as a career option.

Of ALL the professors, Mr. Lee and Mr. Armstrong are the two best instructors I've had at CCSF and beyond. If you care about science & not go through the motion, Mr. Lee holds the standard. If you do your homework, put in the time to review, "have grit," and most of all practice, and not blow off opportunities, you will get a good grade.

Professor Lee goes beyond the curriculum, in a great way. He teaches comprehension, so if you are planning on memorizing a bunch of formulas to get through then not the best choice for you. His passion for Calculus is apparent. If you open your mind and put in the work, you'll experience the true beauty of calculus.

Professor Lee definitely has a deeper understanding of the content, and sometimes digresses in a way that clearly shows his passion for the subject. The way he explains math is in a very unconventional, yet somehow understandable and engaging way. As for homework, as long as you keep up and seek help when needed, you should do well in his class.

Definitely a rigorous course, even for Statistics. Since professor lee likes to teach the calculations by hand, class was structured in a way that calculators were not needed. Homework is a bit tedious and takes up a significant amount of time. My advice is to do a couple problems a day and not to cram! Overall, he's a knowledgeable professor!!!

four tests plus final, test grade is based on grade distribution of all students. Easy A if you do all your hwk. I missed a lot of classes but i did all my work still passed all my tests and hwk with A's. The last chapter was beyond this class in my opinion, but we did not really have it in the final.

Difficult math class and lots of hw! Professor Lee is nice and cracks a couple jokes here and there but the way he teaches is unconventional. Let's just say we didn't use calculators.

Ted's lectures and notes are inspirational.I don't think I'd had majored in Math without him. Ted might make you work hard but it's so enjoyable that you won't feel it's work!

If youre pursuing a science major I would definitely recommend him. He gives you more material than what other teachers would, but also get ready to do double the work!!

Prof Lee is highly knowledgable - his homework problems always extend the material to other areas of math and science, so just doing the homework will introduce you to many concepts and ideas not specific to the material, which is great. There is a significant amount of homework, and many of the problems are quite hard. Prof Lee is a stickler.

Mr. Lee is by far one of the best professors I've met in ccsf. His lectures are super clear and the notes are awesome. Homework takes hours to finish but it helps you understand the concepts better. 4 tests and 1 final, homework grade can replace the lowest test grade. His classes prepare you well for your future classes. Highly recommended!

This guy is a GEM of the ccsf math department, inspired me to be a math major. HW is the hardest thing I've ever done prepare for late nights. Go to office hours, he will always help as much as he can. Tests are doable, HW is the hardest and most valuable part. Uses the textbook, but his notes are amazing and will help you deal with the HW.

His class is hard but for a good reason. He wants his students to be prepared for calculus. I took precalculus three times but his homeworks have been the hardest ones so far. They really make you think and be careful and he really wants you to understand the concepts. If you really want to learn math, I suggest taking his classes

If you want to be prepared for future math classes, take Mr. Lee, if not I would go with another professor. On average, I spent about two hours a day doing hw for this class, half of which I was unable to solve. However during office hours, you can ask for help and he will write it all out. So long as you do all the hw, the tests are very doable.

If you want to open up your eyes for Math, take Lee. I never knew Math so well until I took his class. Everything becomes sparkling clear, and it will prepare you for your life about understanding Math and the world. Personally, I think it is like a once in a life time chance to be able to have lectures from Mr. Lee. Amazing is the word.

I took Mr. Lee for 110B in Fall 2023 and 110C in Spring 2024. I'd have to say my understanding of math has never been greater. The tests can be challenging, but very doable given you study the practice tests diligently. He can go very in depth with the topics he's teaching, and probably has the greatest intuition of math of anyone I've seen.

His lectures are very concise and clear, and he is very passionate about them. Often at the end of the lecture his hands would be pitch black from erasing the board. His grading consists 6 items: HW grade, 4 test grades, and the final grade. Tests are challenging but he gives you practice tests. If you do good on the hw it will replace a lower test

Mr. Lee is like really knowledgeable in math. Like, REALLLLY. Like many others said, he is a harsh grader in general but teaches really well. His notes are also really good, definitely can use for review in the future. He does run out of time usually in lectures also. Overall not bad prof, would take again for calc 3 if I could

Professor Lee teaches with a unique approach, providing extensive material that requires diligent study. While the workload can be demanding, students who engage with the content and utilize resources like unstuck study find the course rewarding. The tests are challenging but manageable with proper preparation.

Mr Lee acquires the real mathematical knowledge. He try to lead us to play with formula and number, rather than just solving the question with brute force. He often open the door and take us into deepest mathematical realm. I very grateful him for teaching me so many tricky to attack the difficult mathematical problems.

He is the best teacher I've ever had. He changed my perspective on mathematics.

if you want to grasp math and are willing to take responsibility for your homework, his class is worth taking. After taking his class, I realized that I didn't truly understand math; I had merely memorized some concepts. But after his class, I genuinely understood the subject matter. And please, students, take his math 130 class; it's fantastic!

This is probably THE most in-depth teacher you'll ever meet. His teachings are meticulous and info heavy. He's also very heavy on the homework and grades with a sharp eye. His class isn't for the faint of hearts, but you will gain a HUGE understanding in the subject once you get going. Also don't intentionally skip his classes, you'll fall behind.

I feel so lucky to have met him. He played a pivotal role in transforming my perspective on mathematics. After transferring from community college, I realized that I was significantly ahead of most university students. His class, Math 130, not only solidified my foundation in mathematics but also prepared me to become a true scientist.

I took Mr. Lee for both Math 110B and 110C. The weekly homework is pretty tough, which usually takes me around 3 days to complete, putting in 3 hours each day. But I don't regret taking his class because as an engineering major, I felt like I learned a lot and very thoroughly.

I took Mr. Lee for Math 110B, 110C, and 130. Although there is a lot of homework, most of it is based on the handouts he gives in class and they are very well planned towards the benefit of the student to do it. His lectures were very in depth and his understanding of the topics are obviously very deep. He also sometimes likes telling life stories.
