Participate in study groups. Review and summarize your notes the day before the test. Be sure to be well-fed and well rested as you go to your exam. After all, the test exists to help you advance professionally. If your anxiety on exam day is moderate, there are several relaxation techniques that are helpful in quelling that beast called anxiety.
Physical relaxation is one technique.
First, sit comfortably with both of your feet on the floor and your hands resting on your thighs. Release all your body tension, and close your eyes and count backward from 10 to 1. Count only on each exhalation, and breathe very deeply from the abdomen. Another physical technique is to clench your hands tightly for 5 to 10 seconds and then slowly relax your hands. Repeat this process throughout the muscles in your entire body.
