Underscoring what the previous posts have mentioned, the more "active" your study, the better. If you are a visual learner, then writing out important points, etc. is essential. And, if you have a good memory for color, use different colored ink to categorize concepts. If you are an aural learner, having someone else quiz you and review with you may help you recall information during the exam because your memory will recall having heard the question or the answer,etc.
Do you have any of your old exams? If so, review them. If not, try to recall which questions and which types of questions were asked. Most teachers review their previous exams, and they naturally format tests similarly to previous ones. Textbooks afford a way to review, as well, since sections are created in them, boldface is used for important ideas, sidebars have notes, questions, etc. So, go back through the chapters to be covered on the exam. So many times another look in the textbook will reveal things that have not been recorded in one's notes.
Studying and then sleeping has been proven to increase memory as neurons connect ideas and information as your body rests. So, give yourself time to sleep in between study sessions. Above all, get a good night's sleep on the eve of the exam.
During the exam, do not stress over one question. Move on, and come back if you have time. Above all, trust your first hunches on multiple choice. That students are usually correct on the first impulse when they take multiple choice or fill in the blank has been proven. As a teacher, I have seen the truth of this study over and over. If you have studied well, relax and be confident!
