Here are some things you can do to prepare for a test—and some things you should not do. • Begin studying well before the test. • Focus on important information in your notes and the textbook. Look for highlighted words and formulas. • If needed, have a discussion with your professor about where your studying should focus. • Review each problem type that may appear on the test. • Try to get a good night’s rest the night before the test. Do not stay up all night cramming for the test. Eat sensibly before the test. • Do not try to memorize everything in your notes or in the textbook, causing information overload. • If needed, form a study group, but do not use the group for excessive socializing.
