Reviews of professor Qian Cheng

Rating: 1.0/5, difficulty: 4.0/5
Cheng is a kind human, but he is simply not a good teacher. His lectures were extremely unorganized, confusing and rushed. He sets you up to memorize the content, not understand it. Practice exams/study guides are NOTHING like the tests. I think STOR 155 is intended to be an easy class, but he made it way more difficult than it should be.

Professor Cheng was clearly knowledgable about statistics. There is a textbook for the course, but you don't necessarily need to use it. His powerpoint slides go in depth about topics and he was always available via email or office hours if there were any questions. His tests were difficult, but gives partial credit. Gives extra credit assignment.

To be fair it was his first time teaching as he is a PhD candidate, but Professor Cheng is a very poor teacher. He was incredibly apathetic and rushed through the content making it more difficult than it needed to be to pick up on it. He put in the least effort I've ever seen a professor put into teaching a course. I'd take someone else.

Cheng's lectures are very unorganized and I honestly did not learn anything from them. I did all my learning outside of the class, on my own. He expects you to know additional things that he does not cover. The exams are not even remotely like the practice, so you don't know what to expect. Cheng makes the content harder than it needs to be.

Professor Chen is considerate and nice. He conveys the content to us in a very clear way. He prepares for the lectures very carefully so that I can understand him easily. When I have questions, he always answers me earnestly. I would like to take his course again!!
