Compose yourself. Relax and take several deep breaths to clear your mind of clutter and stress.
Cover the most difficult information first.
Review the main points, general ideas and broad, sweeping concepts. These are essential to understanding the more detailed points on which you will be tested.
Skim lecture notes and assigned reading materials (see 'How to Read Quickly and Effectively').
Take breaks to stretch, relax, eat or exercise. As a general rule, you should take a break for 10 minutes out of every hour.
Review the main points and concepts one more time and then get some sleep before the big exam.
