Go over your notes for each exam and convert them into a study guide, and then read over the guide until you feel confident. To test if you’ve really learned the material, ask yourself questions or make flashcards. Before you start studying, make a list of the exams you need to study for and rank them from easiest to hardest. Study for your easiest exams first to get them out of the way. Then, devote the bulk of your time to studying for your hardest tests.
