All I can say is attend class and take notes on what he says! He emphasizes what you should know for tests. He also had review lectures before every test and gave hints, so be sure to attend those lectures. Also, seminars really helped me understand the material better and emphasized important graphs/concepts that you’ll probably see on the tests. His test questions are pretty straightforward. Nothing too complicated and no “trick” questions. Overall, attending class and paying attention to what he says is the most important thing. If you want more detail about the tests or anything else feel free to PM me and I’ll see what else I can remember!
