I have to study for 2 tests tommorow, bleh.
What I do is write it down. For some people writing it helps them remember. Also get a person and try to explain to them what your test is on and some of the questions and make them ask questions about it. [ex. Well my test is on this book by ___, and it's about a boy and his dog... blah bla.] Then the other person asks "who are the main characters?" and so on.
