Other study hints:

Re-write your notes! - Ask questions in class! - Study with a friend. - Quiz each other. - Get a good night's sleep before the test.

Study Hints

Try concept mapping: Get some blank paper (try a recycling bin, use the back). Write down a key term (biomagnification). Now, draw lines from the term to blank areas on the page. Begin to add new information – 4 things that are necessary for biomagnification, 4 things that biomagnify, etc. Make links to the new topics. Continue until the paper is full. Start over with a new term.

Get in the Mood: Study early and often. If you can’t find a quiet place, tune out the background with lively, non-vocal music. A fast beat keeps you motivated; vocal would distract from processing language information (reading). Try Jazz or New-Age music, the same sort of thing you would listen to for jogging. David Sanborn, David Benoit, Peter White, Spyro Gyra, Mannheim Steamroller, even John Tesh (really) are all good bets.
