Sweatband Method

Works better if you're an athletic person.

1. Start to wear a sweatband a few weeks before the test, as if to make it seem like an item that you're going to wear periodically.
2. Prepare a mini sheet of paper and attach it to the sweatband.
3. Check your notes by taking it off and then when done, put it on the same wrist.
4. Get rid of the notes, and continue wearing the sweatband for a week or so.
