Study! Do not put it off until the last minute. If you hold off until the night before or, even worse, that morning, you are less likely to retain all of the material because of stress. Just maintain a relaxed and light mood, then you won't feel stressed. Start studying when you find out about the test, or the week of the test. Get a study friend: Get a friend, family member, or even your girl or boyfriend to make practice tests for each other. Not only will this improve your grades, it will maybe (60% chance...) improve your relationship! If they say no, do not be mad at them. They are the ones missing out. However, remember don't get a friend who will goof around instead of studying!
