Had 31B with him and I think it was his first quarter teaching but he spoke with a heavy korean accent and wrote kinda small so sit in the front and still read the book. He actually took notes from the book...

I had him for the first semester he was teaching so some of these other reviews may be better because he learned from his mistakes.

2 midterms and a final, whole class was curved. Althought he had practice midterms and finals which were really really helpful (like the best)

Received a B+ even after attending every class, discussion, and took notes out of the book.

His homework problems are really challenging so make friends in class to do it together.

Had him for both 31B and 32A. Pretty good professor overall. He lectures clearly and is easy to follow.
His office hour is super helpful since he is always willing to show you the answer in homework(which is closely related to the exams), and present some methods that can be used to solve problems in the exam. Be sure to do his practice exams!!!!!

Got A's in both classes.

Math 31B Fall Quarter. Worst class of my entire life. I put countless hours into this class including outside tutoring and still only got a C+. A lot of people do not pass the class. Kim was no help and very difficult to follow and understand in lectures. Tests were unreasonably difficult and homework is graded by accuracy. I would not recommend this class/teacher to anyone.

Pretty good overall. He does leave out some little things (for example, when doing substitution by parts, how to pick the u. There is a specific method but he says you just have to know how). But he covers the main concepts well. Always do the homework; it's a bit challenging but very helpful for the tests. His tests are extremely fair, occasionally he'll throw in a new kind of problem that's difficult but I think his grading scheme makes up for that. Very very slight accent, nothing to worry about. He generally seems to care about his students and wants them to do well. Overall a good professor, I would take him again without hesitation.
