You can try any of the following techniques shown below:
Write the necessary information on your fingernails with a pencil, stick your hands IN YOUR POCKETS when you walk into the test if you have many notes on your nails. Then during the test when you come to a point where the notes on your nails will be useful, pretend to pick them. Then once note is used stick your finger in your mouth and lick your nail. This makes your notes disappear. This method is great during Geography tests, because you can make maps out of your fingernails (when put together) then quickly get rid of them.
If you are taking a scantron test, (fill in the bubble tests often used in standardized tests, but also given by teachers) it will be graded by machine. However, you can fool the machine. If you are stuck between two answers, simply fill in both bubbles. The scantron will pick up on the darkest bubble. When the test has been returned to you and you are checking over it with the class, pay attention when they give the answer to the double-bubble question. If the answer that the machine marked was correct, simply erase the incorrect bubble to make it appear as if you changed your mind on the test. If it marked it as incorrect, slightly erase the incorrect answer and tell your teacher that the scantron machine made an error and marked the less-darkened bubble. This works more with gullible teachers; some have been able to fool teachers many times with this method. However, do not do this on every test as your teacher will catch on eventually.
Cell Phone Method
Put all needed information in a note on your cell phone. Put your cell phone on your knees, where the teacher cannot see it, and when you need an answer, look down at the note you typed. Make sure no one calls you. Or get a friend that can TEXT you the answers on the text, but be careful with teachers!
Toilet Tank Method
Note: This must be prepared beforehand.
Go to the toilet, and...
