Mutlivariable calc: very good teacher, gives many examples especially for applied math. Interesting and entertaining, explains things well, somewhat challenging but not hard.

Connects much of his teaching in this class to MA225, even though it is not a prerequisite, if you didn't take MA225, this will be a hard course but be willing to meet during office hours for much needed help if needed. Lectures are entertaining but matierial dry, very short and easy homework, tests can kill you because they are "outside the box"

very good professor, he's fun and makes jokes all the time. Everyone shows up for class 'cause he's very fun to listen to, it's also easy to understand. TAKE HIM !

Extremely enthusiastic professor. He has an encyclopedic knowledge of math and math history, so lectures can be really funny and interesting. The class sometimes felt a little disorganized, and it wasn't clear what sections of the text to look at. But overall a good class taught by a very good professor.

This was the 2nd class I had with Chung and I love him. For his linear algebra class, it's very important to go to class though or at least get class notes from someone because his tests are much more like his notes than anything that is in the book.

Chung is really good professor who does lots of examples and explains things well. Tests are hard but not unfairly so, and he is quite generous with final grades.

Great professor! Really easy to understand and he is very entertaining! I felt like I was learning linear algebra and the meaning of life at the same time.

He's OKAY. I never understood why everyone loved him so much. He explains things very clearly, but he always comes in 10-15 minutes late and then rushes everything at the end. The tests are manageable but they're so much harder than the questions in the textbook. The TA, Wes was amazing though. Class average is pretty much a B.

Professor Chung was my MA226 and MA242 teacher. He was amazing and I am so grateful to have had him as my professor. We'd talk about dental school during OH!

Chung is awesome. True, he is a coffee addict (no joke) and will sometimes go off on random tangents during class about who knows what, but it just makes it more entertaining. Do the homework (not collected) and tests are easy and straightforward. Also come to class, it might help your grade. Glad I took him over the ENG linear algebra prof.

I have calculus background in high school, so he is pretty good if you have prior knowledge. He is always late to class (except exam dates) and he lets you out early once in a while. He is pretty clear explaining concepts and sometimes funny, although he can be distracted by his own stories. his TF always seems nervous and has a heavy accent.

Great professor. Late to class always - but he knows it. Will help you as much as you need if you show the effort. Funny, too. Level-headed. Take as many classes as you can with him.

Great and fun professor, loved his class. hw not mandatory, and tests are not impossibly hard if you actually go through homework questions and stuffs. : )

Chung's a great professor. Very entertaining in class (loves Spike TV and Starbucks), which is important with a subject like math. He is very helpful if you go to office hours. Go to lecture and do the HW problems (not mandatory) and you'll do fine -- the tests are based on in-class material and HW problems and aren't that difficult.

Explanations are clear (sometimes very entertaining). A word of advice: do your HW (the odd and even exercice numbers from the book) and you'll do great on the exams. Math with Chung was a pleasure.

Chung was a really good teacher. He had lots of funny and interesting tangents and would joke around a lot. His tests would come straight from the book. The grading for the tests was extremely fair. I didn't learn that much because I learned most from AP Calc AB but the new information was easy to understand.

Awesome Professor...really funny, loves math and science, keeps class interested even in the morning. If your taking Diff eq, take it with Chung. Exams cover what you learn, really easy grading, and great profesor

He takes a difficult class and makes it straight forward. Take good notes and do his practice exams and you will ace every test. Also really laid back and entertaining in class.

At first you will find him easy, but that's not the real case. I actually don't quite agree with his teaching method. No homework, no quiz? Not helpful with Calc. If you want to be interested in the subject and having fun taking class and you are really self-motivated, then you are fine. Otherwise stick to someone who seems to be demanding.

Chung is a great lecturer & great at explaining concepts. I especially like how he mentions applications to topics. However, his teaching style made learning very difficult. There are no quizzes and no homework assigned. If you are very self motivated you'll be fine, but I for one need to structure that this class lacked.

I had him for Calc II and loved his class so much that I had him again for Calc III. He teaches by doing examples, and offers a great way to both find your answer and to evaluate it intuitively.

Dear everybody who said there were no homeworks: homeworks were assigned for every section covered in class and were thoroughly answered in discussion. Where were you then? Chung is a great professor for multivariable, and is very clear. The only daunting thing about his course is the final is worth 50% (can't screw up there!) Take him.

Very funny and fun to have class with. Explains pretty well. We didn't cover as much hard material as some other multivar classes. Beware of test grading though, he takes large deductions for small mistakes. No collected HW or quizzes, but don't blow off the practice problems (it'll save you last minute studying.) Book used for HW only.

Really nice teacher. The class is not easy but chung is very funny. You need to go to the lecture and do the homework

Do not take multi with chung, worst mistake of my life! He's a nice guy, he explains well, and if you go to office hours he's helpful, BUT his tests are INSANELY HARD, nothing compared to the assignments. DONT TAKE CHUNG!

Chung is the bomb. He is really funny in class despite being a little hard to understand at first. He moves fast during lectures, but his examples and test q's are straight from the textbook problems that he assigns. He tells the class exactly what's going to be on the exam and is very straightforward. Go to class and discussion and its an easy A.

He is the best! He is hilarious and makes lecture interesting. He goes really fast during lecture and I've found its easiest to get help from other math tutors rather than him because he goes just as fast in office hours. Do the homework because his tests are the homework questions.. most of which he goes over in class.

Chung is THE BEST. Not only is he a great professor, but he is so fair. There are no surprises on his tests but between his lectures, office hours, and discussion I feel like I've learned the content really well. He even makes it fun to class with little anecdotes. Best prof at BU.

He moves through material quickly, but explains his examples well and is really funny in class. His tests come straight from the lecture and homework problems, often the exact same, so make sure to do all the homework. Also is tough with partial credit initially, but you can get a lot of points back on a regrade if you submit a regrade request.

Ken is a funny guy but his exam is a little bit hard and he moves material so quickly. Make sure read the textbook.

He is realy funny at first, but then repeats the same jokes. He is the first professor who I can actually listen to while teaching math. Normally math lectures are useless to me, but somehow he makes things clear without me having to try the problems myself first. Do the homework problems because the tests are based on those.

Homeworks are optional and the your entire grade is based off of the exams. I never did any of the assignments for this class and studied by solving all of the questions he had ever assigned for homework the week before the exam. I think if you pay attention in class and do at least as much as I did to study you should do really well.

He is very straight forward with his expectations. If he says something will be on an exam ... IT WILL be on an exam. He definitely does a great job teaching with what he expects (i.e. if you have never seem something before, odds are you skipped class) because he teaches what he tests. Overall, great. Would take again, for sure.

I was very worried about my whole grade being based off of just three exams, but it worked out! He is very clear about what topic he will be teaching, and then he will do example problems. If he goes too fast, just ask how he got to a certain step. When he says something will be on the exam, it will be. Make sure you understand the problems he does

Chung's tests are hard. He goes over material really fast and doesn't collect hw. Your grade is based on three tests, which I am not a big fan of. He assumes you know your calc 1 and pre-calc stuff well. Sometimes his hw becomes really hard to keep up with because I have hw from other classes as well.

Chung is the man. He tells the same three jokes every lecture, but his lectures are amazing and very inspirational. He puts everything you learn in context and all the questions you will see in the exam he definitely emphasized or is straight from the homework problems.

Chung's awesome. Puts everything in context so you never have to ask "why are we doing this?" Makes you see why math is important regardless of major. If you ask for help, he's more than willing. He goes fast, keeps you on your toes.

One of the best math professors at BU. Make sure to do the homework as they will show up on the exam as well. His lectures are the best. They cover all you need to know for the exams so try not to skip any of them.

If you don't go to class, you will fail. Does not teach out of the book. However, his tests are a direct representation of what you learn in class, so if you do attend class you will do fine. Funny guy, so lectures aren't bad. Also, is extremely biased towards Math/Engineering/Economics/Physics majors. Looks down on liberal arts.

Only half the class goes to the lectures and you'll probably do fine if you don't go because it's a relatively easy subject, but most test questions are straight from class. If you go to class he gives you secret tips on what will be on the test because he hates when people don't show up. He wants you to do well in the class and is very clear.

Awesome Prof!

He is not a tough grader, however, gives reasonable questions that he mentions in class. His lecture is hilarious and you will really into it. DO NOT SKIP A CLASS OR YOU WILL BE LEFT BEHIND. He will curve or give extra quizzes for giving extra points. I am not regret taking it.

Grade was based on three exams. Two midterms and a final. He is passionate about what he teaches and, if you ask, will help you, but he will make sure that you've tried to help yourself before he does anything. It was difficult because the grade was only based on tests and if you are not a good test taker, you're screwed.

Chung is honestly so amusing. He will say some of the most random things you have ever heard, but honestly he woke me up at 9:00 am. His teaching style is ideal for those who are self motivated. If you need someone to hold your hand to study and do homework maybe you should stick to the "fluffy subjects".

He was a pretty funny guy, which made lectures less boring. He goes a little fast, but it's easy to keep up. All his notes are on the board, so it's necessary to go to lecture. Tests were very straightforward, and looked exactly like the examples in class. The homework is optional, but DO IT. It helps a lot when studying for the exams.

He made me love Math again.

I loved his lecture style - he's funny and always connects the topics he's covering to applications in other disciplines. However, grading is based only on exams, and the exams are short so small mistakes can leave a big dent. But the exams aren't bad as long as you actually do the homework. Some questions are pulled straight from the textbook.

He's super straight forward. Do the homework, get an A. Also he is the funniest professor I have ever had

He goes very fast in lectures (I mean, it's 442, expect faster pace than 242), so make sure to take notes as he speaks. Grades are based purely on exams, and the exams are not that easy, but curves are good so no worries.

He is very clear and funny. Although the jokes might seem childish sometimes, but that's just the style. He often says the use of certain type of calculation, which is very useful. If one can study hard, one will get A; unlike some subjects, no matter how hard you study for them, you can't, because the questions themselves are bad.

I took Professor Chungs MA225 in 2017 Fall. He is very hilarious. Always shows off his bad Spanish and German. 500 points for entire class (200 two midterms, 200 Finals, 100 homework). Attendance is NOT mandatory. Homework is based on PARTICIPATION as free gift! He goes over material too fast! But overall I recommend to take his class. Got A-

Gets lots of negative reviews because of his tough style, but if you put the effort in to meet with him he is very helpful and understanding. attend lectures and do the homework problems religiously and you will do well. no gimmicks, what he tells you will be on the test is what it is. go to all discussions for 100 points.

Tests are problems straight from the textbook and if you pay attention in lecture you'll get an A. He is hilarious and makes the material interesting to learn. Discussions were unhelpful though but the quizzes count for your grade.

Depending on how you learn, Chung's lectures may or may not work for you. He focuses on examples rather than theory, but still tries to explain the concepts with hilarious gestures and excellent jokes. The class grade is based on 2 exams, attendance at discussion, and the final. Don't worry much if you screw up one exam, he curves well at the end.

Never required to go to class. Gave great lectures and examples. Always happy to re-explain if you raise your hand. Sometimes goes too quickly through his examples, so you need to do the readings beforehand or be prepared to ask a lot of questions.

Your grade is made up of weekly (super easy) discussion quizzes and 3 midterm exams. No finals and no homework. Chung was super funny and even though lecture was not mandatory, he doesn't post any notes from class so you want to go so you don't drown. Loved him and his exams were very fair. He made college math bearable which is an impressive feat.

You will learn how 16-year-old young newton solve calculus with paper and pencil.

Chung is such a great professor. He is funny in lecture and is clear and is open to being asked questions in lecture until you understand. He gives "hw problems" that are optional but literally if you do those then you will do good on the quizzes and the tests as they are essentially the same types of questions. Such a straightforward and funny guy

Prof. Chung does a great job of connecting MA 225's content to other math courses that use it, and you can tell how eager he is to get his students to enjoy math. His lectures are mostly focused on working through examples, and he loves to use past exam problems to illustrate concepts. The content is interesting, and he's a hilarious lecturer!

He is such a good professor that he will answer every question super detailedly. Concepts and calculations are well explained. Lectures are easy to follow. No homework but have one optional practice problem per week. Lots examples during lectures which are extremely useful. Listening to the lecture and you will get an A.

Calc is a tough subject but Chung made it one of the best. He's honestly so nice and so funny, makes the class interesting and enjoyable. He also cares about your grade and tries to do what he can to make sure you get a good grade. As long as you go to class and put in some work outside of class, you'll do great. Great guy.

He's entertaining and passionate during lectures, and wrote out the notes real time so it was easy to follow (not prewritten). Very reasonable exams, everything was straight from lecture, just make sure to write down all the examples given. Curve was very reasonable too. No graded homework, only 3 exams, they were fair but it's not for everyone.

He is willing to talk with his students outside of class and really help them understand the material. He also takes the time in class to connect with his students.

Professor Chung is pretty funny and relatively easygoing. The class material was not too hard and he really took time to explain things and answer questions. But he did start to rush a bit at the end of the semester. Your grade is only based on 3 exams (homeworks aren't graded, only recommended). Exam problems are similar to homework problems.

There were no assignments and only 3 midterms during the whole semester. After getting feedbacks from students, he added some extra credit problems and it is easy to get an A if you just listen to his lecture. Maybe he is not such a good teacher, but is definitely a good choice if you want to get a good grade without working so hard.

By far my favorite math professor and class so far. Lectures were engaging and easy to follow as long as you keep up with them. There were 3 fair yet challenging midterms, no graded HW, and about 10 extra credit assignments. The HW was the best tool to learn the material outside of class and it felt very meaningful rather than busy work. 10/10

Ken Chung is the best math professor I have had at BU, coming from a math major. He may seem tough at first, but most of the policies that seem strict are actually flexible (except no late homework) but he just has to say them bc of the math department. He cracks jokes throughout the lecture and is actually so hilarious. 10/10 recommend.

The only grades are the midterms, but they only cover material from lecture and the optional homework. The exam problems can be a direct copy from these two sources, so attend lecture and do the homework if you want to succeed. His lectures can have tangents and he loves repeating the same two jokes but the course feels very light-hearted.

As much as Chung receives hate for repeating the same jokes throughout each and every lecture, I think he was one of the best lecturers I've ever had mainly because the doesn't try to overload you with work. Content and material drew heavily from EK 103 during the middle of the semester. Overall, highly recommended.

Professor Chung is seriously hilarious! Go to lectures and you will have a great time. His humor makes the material bearable. His exams are also very straightforward and go off of the textbook, so you will know what to expect. Definitely the best math professor I have had at bu

I really enjoyed taking this course with Professor Chung because he always found a way to peak our interest and linked course materials with real life matters and how we could use what we are learning in math in our own major. However he was late most of the time and we did not get to finish everything

He really wants to give out As to everyone, just put in the effort to study. The midterm was all easy, some questions he just took from the textbook. There's only 5 questions per test, each worth 20 points. I went to maybe 75% of the lectures and enjoyed all of them (yeah he tells the same jokes but I appreciate him trying to make the class fun!)

If you study and go to class you should have no issue. Prof. Chung teaches well enough and tries to make the class entertaining, even if not all his jokes land. He gives the class extra credit opportunities a lot. Homeworks are not graded, but you should do them to learn the content. Exams are more than fair. Taken Spring 2021.

Fun lectures and clear passion for subject. Only grades are the three exams, so make sure to do the homeworks. Is funny, especially for a STEM professor, but uses the same 6 anecdotes all semester. Always simplify C(n,0) to 1 and C(-n,r) to C(n+r+1,r)*(-1)^r.

Best math prof at bu by far. Lectures are entertaining, he makes lots of jokes. Super fair exams that are straight from the homework.

No final, only 3 midterms. He does a lot of examples in class, so the midterms should be fine if you use your lecture notes and hw problems to study.

He has the funniest sense of humor ever I love him so much lol. His quizzes and exams are easy if you study. His lectures are very conceptual rather than just writing down notes, and he gives lots of examples that are similar to test/quiz questions. He will definitely skip over some steps when he's doing math but just ask about it and he'll explain

Extremely easy exams that relate exactly to previous years exams which he reviews. Homework is light, worth 25% and 3 midterms worth 25%, no final. It's a challenge not to get an A or an A- in this class. Linear algebra is covered a lot but not needed to know before this class, I had not taken it.

Loved this professor! He was super funny and class and the exams/quizzes were extremely easy especially if you have taken calc.

As long as you do the textbook problems and understand it, this class will be a breeze. Also Professor Chung goes over sample test and quiz problems the lecture before the test. I used to hate math and sucked at math however, Professor Chung made it very clear what you needed to study for the test and quizzes it was basically a freebie.

Best professor I have had at BU; his lectures are very clear and he always tries to make the lectures entertaining by his jokes that he makes, and he grades fairly. Just do the homework and pay attention in class and you should be fine.

I loved Prof. Chung! He's funny and is clearly passionate about math. Hw isn't mandatory, but def do it and ask questions in office hours because hw questions are what's in the exams. He cares more about you understanding the concept than just memorizing it. Exams are a big part of your grade, but they are curved really leniently.

He brings a lot of humor and enthusiasm into lectures. While his organizational skills are bad, he is still a competent and effective professor. Midterms are more than fair. Some problems came straight from lecture notes. Honestly, I can't think of another math professor who still provides lecture recordings in the post-covid era besides him.

Professor Chung is awesome. His lectures are interesting, though it is undoubtedly that you need to make efforts on what he has taught after class.

The best thing of Chung is he provides recordings for every single lecture, and I think he gives a final curve to the whole class at the end. Midterms are just lecture notes and HW problems, if you can understand all of them you should be fine. However, be aware of the TA, there are 5 quizzes, and many of us only got 70-75 in average.

His exam is not too difficult but it does take some effort. Class recordings are very helpful.

Very good lecturer. As long as you understand the lectures, the exams will be super easy. He tests on concepts, and is very clear on what the exams will be like.

Professor Chung taught the class well. The lectures might be a bit confusing, so give urself a brief preview of the topic before the upcoming classes so that you can understand better what he says in the class. Tests are really easy and big curves were given so it's easy to get an A when you receive like 80% on the test paper. Big shoutout to him.

Professor Chung's lectures can be a bit confusing, but with some preparation, the class is quite manageable. Exams are challenging but curved, and using resources like the textbook and Unstuckstudy for study prep can really help. Overall, an engaging professor who cares about student understanding.

Five minutes late, Professor Ken Chung arrives, Declares math, science, eng'r the only real drives. “Give blood, sweat, tears or choose poetry instead!” Yet with clear visuals he fills every head. We love how he maps dimensions to our sight— Ken Chung turns tough math into pure delight.

I truly think he is a W guy. He is sweet. His jokes may get old, but he is experienced smart for sure, but you may not see it unless you talk to him. He is soooo nice with grading. for MA 225, Ungraded homeworks. quizzes every week, those quizzes super easy tho. He cares about your success. just talk to him, hes super sweet. He is open to teach u.

Lectures were engaging clear and helpful if you showed up. He made a lot of the same jokes but he was a joy to take. I would recommend you learn from him when you can. My only complaint about the course was the TA that taught the semi-required discussion blocks was horrible, but that seems out of his control.

He made learning calc 3 enjoyable

Chung is great! Cannot go wrong, keeps tests pretty easy so long as you put in even the slightest bit of effort.

Very entertaining, but hard to follow sometimes. I liked his attitude towards math and life in general.

The Absolute Goat. Most entertaining lectures ever, great at explaining difficult concepts. Tests were unbelievably easy and class was curved. Only downside was that the class was very disorganized. He had to kind of really rush through content at the end to get through it all, left me a bit confused. It's fine because the exams are so easy though.

If you are naturally good at math take Ken Chung 1000% because he is hilarious and his lectures are entertaining. This guy is definitely an experience with crazy takes and out of pocket humor. If you do struggle with math do NOT take this class as the grade is very dependent on only three small exams. He does however give out lots of extra credit.

Ken Chung is amazing! My favorite professor in the math department! I only went to like half the lectures and watched his recordings for the others, but his lectures were always really funny and good. Prompt with replying to emails and supportive at office hours. Entire grade is 3 exams but a lot of questions were almost verbatim from lectures.
