Plan for Exams, Don't Cram
A lot of people joke -- or brag -- about waiting until the last minute to study for a test. Don't buy it. Cramming makes you too stressed-out and tired to think straight. Stresses can add up to real pain. You can't sleep, you gain weight, or feel depressed.
Tame your stress with a study schedule. Review one chapter or set of notes at the same time each day, starting 1-2 weeks before the big test. You'll feel relaxed and well-prepared!
