Stuart Gill is by far the best Instructor I had this year. He's extremely laid back and friendly, and thus easy to talk to and get to know. His class consists mostly of delving deeper into the lecture material and working on Habits-related problems. Usually in-class we don't do much work, just kind of sit-back and listen to him, with the occasional problem being done. If you answer wrong, hes completely cool with it. He also likes to joke around a lot and is actually pretty funny. His class actually requires THINKING and READING of the lecture/text materials, but you never feel like you're doing busywork and the laidbackness is totally worth it. You can often even turn in assignments late, and he lets you write a one page essay on the topic of your own choosing to replace one of the homework assignments.
