He is extremely articulate and organized in his lectures. Although the class was unexpectedly difficult, the grading cutoffs were lowered at the end as to match the previous year's distribution.

The entire class is him summarizing chapters in the book and him doing the examples incorrectly on the board - so if  none of the students who are learning the material catches his mistakes, everyone ends up writing and learning incorrect solutions.

One midterm in Math 331 was tough, but you can do well by studying the practice problems, which the exams closely follow.

A 1.7/5 is incredibly harsh for him, because he wants his students to learn first above all else, so he goes over proofs to help us understand why the stuff we learn works the way it does.
