Sorry Raion but "Test Anxiety" is not cured by studying at 4AM and eating breakfast. It's a much deeper problem than that. My wife struggled with it all through high school and college. It was so bad that I refused to take any classes with her because she would get pissed if I did well and she froze. It's largely a matter of confidence. Confidence that you have studied and do know the material. Confidence that the instructor (probalbly) isn't trying to trick you with the wording of questions. Confidence that if you do happen to perform poorly that it does not mean you are doomed to a lifetime of asking "would you like to Super Size that?". Once you have confidence in yourself you can relax and take the exam with no difficulty. Sadly, with some people it is very difficult to get that confidence.

I did a quick search on Google and found some good suggestions...
