**Comment**: In short, you should think twice about taking a class with S. Evans if you are not comfortable learning the material on your own and solving challenging problems on exams. Stat 157 is a topics class. In our semester, we followed Stochastic Calculus for Finance I: The Binomial Asset Pricing Model by Shreve. Evans' lectures generally consists of reading off of his slides, which are copied word for word from Shreve's textbook. He does make some verbal comments and writes some things on the board, but those don't really add much beyond what's already in the book. The weekly homework exercises are straightforward, though making people do homework in groups of 5 people is a bad idea. Since only 1 or 2 problems are assigned every week, generally only 1 or 2 people from each group do the homework and the rest of the group learn nothing. Also, almost every problem on the final was challenging/interesting, which is fine by me, but many students found this to be distressing. So it might be better if he added a few more routine problems to the exams. Evans is somewhat monotonic, though occasionally displays a dry sense of humor.
