Explanation:

Summary: Multiple spaced exposures is the key. Use surveying to cut down on your reading time without missing important ideas. Create a detailed notebook about how to solve all your equations and formulas. Review everything in full as many times as you can before your test. Test yourself at two-week intervals. Always sleep well, eat well, and exercise daily.
