Winter 2022 - The thing I liked most about Prof. Killip is his tendency to use simpler words instead of formal vocab. His energetic lectures made this class my favorite calc class. Exams and homeworks felt pretty standard, although I did take this class in Winter 2022, which had COVID perks.

32B is probably the hardest lower div math class. The class is very abstract in a sense, because it requires you to be able to visualize in 3D in order to do the problems. Integration is also not a very easy concept in calculus, so if you had problems with it in other calculus classes, this class will be hard. Kucherenko does have an accent, but I feel like she did a good job covering the material and trying to explain things the simplest way possible. IN the beginning she would do some proofs and go over the concept, then do examples. Her lectures are very organized. Her midterms were pretty hard, and her final was pretty hard too. She's definitely NOT an easy teacher... but if you practice from the book and review everything before the tests you should be ok. 32B is about twice as hard as 32A, and it does require you to get a solid grasp of the concepts and know what you're doing rather than just blindly doing problems. If you don't know what you're doing and why you're doing it, this class will make you suffer. Final grade in class: A

Winter 2020 - Sangchul is probably one of the best math professors I have ever met at UCLA. Although he just received his Ph.D. in 2019 and became a first-year lecturer, he really knew how to be a good teacher: he gave clear lectures, detailed lecture notes, and extra office hours. Whenever I have questions and emailed him, he would reply within a day with very detail explanations (even with graphs!). Midterms were fair and easy and the final was long and hard (but it is open book, open notes, and you have a whole day to complete the exam). I believe no professor else would be such cute to draw smiley faces in lecture notes and such kind to give more than one practice test before examinations. 32B is a very hard class, and Sangchul has made it much easier for me. Definitely choose him if possible! Overall: 5 Easiness: 4 Workload: 5 Clarity: 5 Helpfulness: 5

Winter 2018 - I'm writing this before the final grades are posted, just trying to avoid possible bias based on a letter grade. Professor Liu has his styles, which is like "computation with tricks" and "inspiration", and you would agree with me if you have attended his lectures and seen the test problems. He always said "this is nothing but just ..." when emphasizing an important concept or a kind of abstract notion in lectures, not so hard to follow. He has accents, for sure. But such pronunciation problems only have minor influence on the lectures as a whole as long as you do not fall sleep and miss something in the transition from one idea to another. The grading scale seems kind of harsh; after all it is a lower division math class: Scheme A: 10%HW + 40%Midterms + 50%Final ( you may find it really easy to understand your final raw score for this course since Prof. Liu gives 2 midterms of 20 points each and a final of 50 points). Scheme B: 10%HW + 90%Final (Final is really hard, not just cumulative in contents covered, but also "tricks". Fortunately, in lectures he covered most of his "tricks" appeared in tests problems. If you find something really tedious to compute, then please think of some "tricks" you may be not so familiar with.

lol at all of you in his 32a. for 32b, basically multivariable integration and line integrals etc, he had easier tests than 32a. he can be hard to understand especially when youre not laughing over teeta, beeta, youshual (usual) etc. his midterms are fairly difficult but his grading policies allow you to drop your lowest one and increase the percentage worth of your final. final was not that bad. a lot of the questions are those tricky homework problems
