Reviews of professor Zili Zhang

Rating: 1.0/5, difficulty: 5.0/5
Professor Zhang never taught the reasoning behind why anything occurred. He just put equations on the board and said to use them. After the first week, less than half of the class showed up and I'm pretty sure they just went to Gavin LaRose's lecture section. I always felt that the homeworks and exams were harder because our professor was horrible.

Math 115  the hardest course I took at UMich. Zili's lectures were very fast-paced, included no teaching on understanding concepts, he just wrote equations on the board and didn't explain them. I took this class in the fall w/ him and got a D (exams are extremely hard), retook the course in the spring with a different professor and got an A.

Compared to the other 3 professors in Math 216, this guy teaches nothing. He only puts some equations on board and briefly explains the concept. You understand what he says but when you do the homework and exams, you will get confused on everything, because he never gives examples nor he explains concepts in detail.
