Much of the information that they knew very well would vanish once I asked them to put it down on a test paper. The students with this problem employed a fundamental law of hypnosis. The will of the student is to pass the test. The student studies and studies and knows the information backward and forward. Then the big moment comes.
Fear takes over the imagination.
All the horrible thoughts that can arise from such a fate start to inhabit the imagination. We fight fire with fire. Tell yourself that you will remember everything you need to pass the test. Tell yourself that you are learning easier and easier, that you relax while you learn. You will read this script over several times before you study, while you are studying and before and during the time you are taking any tests.
