Cheating time
As we have seen, there are many ways to conceal your cheat sheet. Some are more convincing than others. The trick is to make it look natural and not suspicious at all. And with this method, you will feel like James Bond after taking the test.

The trick is to find an old watch lying around the house, open it, and stuff all the information you need inside of it. During the test, you will raise no suspicion as it will only look as you are nervously checking on the time every once in a while to know how much time you have left to finish the test.
