Professor McDevitt is definitely a smart guy and knows his material well, but his lectures can be hard to follow if you don't have a good view of the board--his handwriting is messy and he doesn't use slides, so sit up front. He does post notes that are pretty thorough and useful for studying though. The practice tests are good examples of what the exam will be like, so if you understand the concepts covered on the practice exams, you should be fine. Overall I thought this class was decently interesting and I got an A for the first time since Econ 1 (and I got a B when I took Econ 11 with McD, so that's saying something)
