His practice exams are almost exactly like midterm/final except for one or two questions on them. Because of this I was fine with skipping lectures and then just reviewing the material that is on the practice exams. We were allowed front and back cheat sheets for exams and he didn't care what you put on them. It was an easy A if you practiced.

This professor is pretty nice and passionate. The exam is easy if you do the sample midterms carefully. I really recommend this.

Cool guy

Heavy accent, boo hoo get over it. He is not that bad, especially when compared to other math professors here. The main ones complaining abt yan prolly are that one econ major friend you have who parties every weekend, and even they got a good grade prolly. Just study the study guide and do the hw, you will be fine.
