What you need: MP3 player, headphones, long-sleeve shirt

Risk level: Medium

Can’t afford to buy a high-tech miniature earpiece? Don’t fret, you can still cheat using pre-recorded audio. All you need to do is position the MP3 player somewhere out of sight—say, your pocket—and run one of the headphones up one of your sleeves with the earpiece stopping right at your cuff. While taking your test you simply rest your head on your hand, hit play, and listen to your audio notes. We recommend you do this one in short bursts.
