#3 One word. Quizlet.

If anyone has ever gone without knowing what Quizlet is, I'm crying for you at night. Quizlet let's you make tests, flashcards, multiple choice questions, and games all based on your study set!

Plus, if you feel as though you're too tired to make a study set, there may be one lying around that someone else made. It's an easy tool to use that limits the amount of supplies you need to buy, and makes everything much simpler.
