CHEATING DURING A TEST #3
This one’s an old classic. While preparing for your next exam, take a rubber band and stretch it out as far as you can without snapping it, and tack it down. Next, write whatever it is you’re having so damn much trouble with on the band’s surface. Once you let go and it returns to its non-stretched state, the writing will be totally unrecognizable. Go to the test with the rubber band around your wrist, and when you need the info simply stretch it out, and there it is!
