Preparation for your test should begin on the first day of class; this includes paying attention during class, taking good notes, studying, completing homework assignments and reviewing study materials on a regular basis.
Budget your time, make sure you have sufficient time to study so that you are well prepared for the test.
Go to review sessions, pay attention to hints that the instructor may give about the test. Take notes and ask questions about items you may be confused about.
Ask the instructor to specify the areas that will be emphasized on the test.
Make sure you go to the class right before the test; it's another prime time for the instructor to give out more hints or the format of the test.
Go over any material from practice tests, HW's, sample problems, review material, the textbook, class notes… the night before.
Eat before a test. Having food in your stomach will give you energy and help you focus but avoid heavy foods which can make you groggy.
Don't try to pull an all nighter. Get at least 8 hours of sleep before the test
Try to show up at least 5 minutes before the test will start.
Set your alarm and have a backup alarm set as well.
Go to the bathroom before walking into the exam room. You don't want to waste any time worrying about your bodily needs during the test.
