Pencil method (easiest method)

1. This method works well, especially if you are seated where no one is behind you. Bring a mechanical pencil to school the day before the test, so it is not too obvious you are cheating. Write some notes on a small piece of paper, and roll it inside the pencil, where the lead goes. Bring this pencil to the test, but have only half a piece of lead in the pencil. Answer the questions you know first, then make it obvious you're out of lead. Open your box of lead, take one out, then open your pencil. Hide the pencil in your desk, look at the notes, then close the pencil. When done with the notes, and test, roll some chewed up gum in the wrapper and throw the evidence away.
