Let me first say that I have never been in Professor Conley's class, so I cannot comment on his exams or grading. However, I have been watching his old BruinCasts as a supplement to my own professor's lectures, and MAN IS HE GREAT! Professor Conley is very clear and thorough, and he has a way of explaining even tough concepts in a simplified manner so that you can actually learn. I especially like the way he helps you visualize mathematical concepts (through computer-generated models, for example). Once again, I cannot speak for his grading, but from his lectures, I think that he is a fantastic professor.
