Jeff is one of the most caring and unpretentious professors I have had here. He genuinely cares that his students are learning and is not as concerned with grading as with participation and actually getting the students to learn. The class was pretty hard, and I can't say that I understood everything that was going on, but he definitely tried to adapt to all of the students' abilities and knowledge levels.
Workload:
Weekly readings (usually short, but dense). Take home midterm and final, both graded fairly.
