Reviews of professor Lei Wu

Rating: 5.0/5, difficulty: 3.0/5
He has the clearest notes among all professors I have seen. He is also extremely enthusiastic about the subject. His lectures were so enjoyable. 

The only bad thing is that his finals are far more difficult than homework and midterms

Extremely boring, by the end barely anyone came to class. MATH205 is simple enough that you can teach it to yourself, so it's not a huge deal. He also didn't take attendance, which was nice since it meant there was no reason to come to class.

Sometimes his accent makes him almost impossible to understand and he never does examples in class anyways
