He is a fair professor and grader. He does make the occasional mistake during his lectures but he knows what he is talking about. Some other people mentioned that he focuses heavily on memorizing formulas but that's not true. He allowed us to use a note card on the final so that we could focus more on problem solving as opposed to straight memorization. Math 31B is not the most enjoyable class but Professor Taylor definitely makes it better.

Bad teacher. Very disorganized. He makes many mistakes in lecture and spends a lot of time trying to correct them. It also feels like he is more concerned with having you memorize formulas instead of actually understanding the concepts. I stopped going to lectures because his lectures ended up confusing me. I would recommend not taking math with this professor if you can.

So far THE WORST teacher at UCLA.
Very disorganized in lectures and we never get our homework back. Don't learn much in the lecture, so don't even bother going to the lecture unless you turn in homework.
We get practice exam's solution like the day before the test, and it is not even complete solution.
Try avoiding him.
