If I know Wu before taking Math 170S, I won't take Math 170S

If you're thinking about taking 170S with Wu, just don't. It'll be better for your mental health and your sanity. If you have to, I will keep you in my prayers.

One of my only C's at UCLA. Absolutely terrible professor. Our TA (Adam Lott) taught so much better, that people stopped going to lecture and tried to get through the course just from discussion + TA OH. Wu is a terrible lecturer and overcomplicated everything, both in terms of notation and concepts. Often pauses during lectures because he's sure that his proofs are correct, how do you not the material taught as a Professor?

Notice that the grade distribution is from 2022, NOT 2023.

worst professor taken for math class; if you want to understand something, or anything, please avoid

Avoid at all costs.

He’s not as bad as people make him out to be. He is a bit slow at explaining things but his explanations are clear. His homework has a very fair length, his tests are within expectation and about what he taught in class. The proofs aren’t even tested. Overall a decent class, could have covered more content

A good professor never give lectures if not prepared.

Professor Wu is very willing to explain contexts to his students during office hours. The course context is a little bit clumsy, but the proof part is not tested in the exam. Upper math class can never be that easy. The only thing you should do is focus on the conclusion of the proof. Wu is a very smart guy, and he focused too much on the proof so students feel lost during lectures. The final is kind of straightforward if you can learn from his homework and formulas.

Overall, Wu is not as bad as the comments said. If you pay much attention to the conclusion of each proof and do well on the homework, you will be fine.

As a prof, he isnt good. He is not clear at all, and made mistakes.
Go to TAs office hours and discussion. The TA will help you a lot, and basically carry the class. They can help u understand stuff. Wu does the opposite and confuses you.
The tests werent too tough which was one nice thing
