This is a technique which I have been using for many years with tremendous success. 
I have been using it with professionals who were failing exams and were not able to receive their professional license. 
High school and college students have also received incredible results. 

The client is taught to enter the three major levels of hypnosis, how to return to them on their own,
how to view the material needed in their studies in somnambulism and how to enter
profound somnambulism to successfully complete exams.

Not only does this eliminate the stress and anxiety that most individuals experience when
preparing for exams but, the person is able to enter the same state to take the exams
that they viewed their material in. This method enables easy access to the
material necessary to pass exams easily and efficiently.

I have listed it in a step-by-step procedure with exact wording for the client.
It is in a four-session format and works best this way.  It includes:
 

Session One Procedures
The setup with a conditioned subject who can achieve all three levels of depth being somnambulism,
Esdaile and the Sichort State.  The setup for a cold subject who has never been hypnotized before.

Session Two Procedures
The Preparation Script
The Recall Script

Session Three Procedures
Retention Exercise

Session Four
Repeat Procedure for Efficacy
