For some reason I had to pick a course they didn't offer, but I took LS 15 with Brunk and it was a little tricky. His lecture are very boring because he speaks in such a monotone, but pay attention because he says material that he might test on that are not on the slides. All the lecture slides are on blackboard and STUDY STUDY STUDY them for the midterm and final, he draws questions directly from them. The main book is good to get a better understanding of concepts, but is otherwise useless. Get to know you TA's and ask them questions about things you don't understand during lab, they're really anal on giving participation points. Try to get Phelan for LS 15 if you can, but if you have to take it with Brunk you can survive.
