Go buy a pack of index cards for a dollar; write the questions on one side of the cards, and the answers on the other.
If you haven't figured it out already, you're making flashcards.
Go through the flashcards one by one, either by yourself or with someone else reading the questions. Once you've memorized one, put it in a separate pile. Continue until you've memorized the answer to every card, and you'll ace that test
Also, it's good to keep in mind that your memory works best if you space out practice sessions from now until the time of your test. Good luck!
