Reviews of professor Li Duan

Rating: 5.0/5, difficulty: 2.0/5
Lectures are pretty good and thorough, though he corrects the powerpoints often. Very clear about what is on the exam before each one, which made it easy to get a good grade on them. He explains things well, and all in all is very reasonable.

Sometimes got lost or messed up examples but usually taught well enough to not need to read the book outside class. He says he cares about you understanding hw so he often posts solutions before due date (helpful and prepares you for test). Tests open note and very close to lecture. Overall decent prof, he does have bad handwriting though.

Probability is definitely not an easy class for everyone, but he made it so that everyone in the class will pass with at least a C. He assigns 2 HW problems every week, but most people do well on them. The exams are kind of hard but he tells you what the problems are going to be on ahead of time. I will be taking STA4322 with him next semester.
