Reviews of professor Yinsong Chen

Rating: 3.0/5, difficulty: 3.0/5
Professor Chen is really nice guy and tries to his best to convey the topics. However, he makes a lot of mistakes in his work and provides not the best examples of concepts. Overall, he is super kind but is just hard to follow, choose a different professor if you are not strong in calc.

Nice guy, bad prof. Teaching was done by examples, where he often made mistakes and moved fast. Math dept requires quizzes, so he gave 3 pop quizzes in a row in 226 then only one all of 227. He gave the only 227 quiz minutes after teaching the content, but I didn't understand without working out of class. Didn't teach everything on final, either.
