You should prepare at least 3 questions for a review session, just in case others are scared to ask first. You should go to the review session because a lot of professors will accidentally slip and give a hint about what's on the exam. So even if it's incredibly boring, suck it up and go. You can always quietly test yourself with your pretty flash cards until something you need to know comes up. While we can't take the test for you, we can offer some subject-specific advice.
Timelines are invaluable.
Write out timelines for each major event so that you can get a sense of cause and effect. You can test yourself by later rewriting that timeline from memory. Highlight the different people involved in different colors. Flash cards are your friends. You have so many confusing terms to learn, that sheer memorization is going to be your biggest hurdle.
