Reviews of professor Pengyu Chen

Rating: 5.0/5, difficulty: 4.0/5
Straight-forward teacher. Explains easily and teaches what you should know. And not much to read at home or use textbook is needed

Rating: 3.0/5, difficulty: 3.0/5
Boring, but as long as you mildly pay attention in class and do the homework, the tests and quizzes aren't hard.

He is incredibly fair as a teacher. There was homework once a week, and he would just lecture everyday. The lecture slides would be posted too, and studying the homework and slides prepared us for quizzes/tests. The lectures were boring, but he really tried to make them more interesting.

Dr. Chen was a great professor. He cares about his students and wants them to succeed. He added a couple of extra points to your overall grade towards the end of semester for doing an extra assignment. His tests were not hard as long as you read through the lecture slides and do the example problems. He also grades leniently.
