Prof. Wu is a good choice if you struggle with math. Contrary to what most people say, he teaches well but he makes note-taking difficult. His exams are easy and if you go over the test examples he gives, you'll have no issues getting an A or B in his class.

If you're not good at math, Professor Wu is the best choice. He's an easy grader and he makes the material much easier. The exams are just like his lectures, Some lectures will go off topic for about twenty minutes, which is very entertaining as well.
