If you're taking his AP classes: be prepared to do a lot of packet work. It's basically like writing a two-page essay every day. Your tests are easy as long as you do the reading and make sure to be involved during discussions. Form groups with your classmates, they will be your saving grace if you're having trouble. At the end of the class, you might not have reviewed enough for the AP test so I'd start two months before the actual test instead of waiting for the Escossio to start.
