Here's my advice:
1. Ask Mr. Block for individual help, since that's where you'll probably learn the most.
2. Make sure the really smart guy who understands everything quicker than everyone else doesn't talk/answer questions that Mr. Block poses...so maybe he'll explain his steps more.
3. Don't study the night before...just review your notes in class everyday...like when Mr. Block isn't talking or doing anything
4. Do the test as quickly as possible (so as to increase your thinking speed for the real AP test) and then double check it.
5. I'm out of ideas...but having number five seemed like the right thing to do.
