Calculator Method

1. For tests allowing calculators, use any sort of text-based memory to record all the equations, notes, theorems, proofs, etc. Create a fake, password protected program and use the text box. No teacher will ever be able to access it. However, most exams do not allow programmable calculators and invigilators may check.
2. If you have a Scientific Calculator, preferably a TI- Silver Edition, you may use the green Alpha button to write in theorems and answers on it. This way, there's no physical proof you ever did anything wrong (unless your teacher sees the theorems or snatches the calculator out of your hand while your working). If a suspicious teacher comes over, you hit Clear and the evidence's gone. The one problem with this method is, you can't use your calculator while the answers are on the screen or you'll erase your answers. So quickly jot down the theorems/ answers (lightly) on the test and hit Clear, in order to work with your Calculator.
