Comment: The class was pretty easy to me. Problem sets are graded on completion. He's very clear in lecture. For exams though, he doesn't write them; the head GSI does. So I guess it depends on how hard the head GSI is. Overall, great professor, good class.
Comment: While the professor was generally enthusiastic and the material presented was no difficult, the head GSI who wrote the exams made getting a high grade more difficult than it should have been. This is most likely due in part to the fact that the percent of grades (A's, B's, etc.) are capped. Overall a fairly average class.
