A blogger in the south wrote about having terrible test anxiety the night before her first exam of the semester. One thing that’s important to remember is that a certain amount of anxiety or nerves before a test is actually a good thing– it gets you ready, “primes the pump”, and gives you the energy to do your best. What happens, however, is that for most people this gets out of hand, and, because it goes unchecked, the anxiety grows and becomes unmanageable (hence, it’s hard to sleep, or think properly). This was shown in a now-famous graph called The Yerkes-Dodson Curve. (As soon as I can figure out how to insert the graph into the post I will– bear with me!). The point is: keep your stress at the right level. Use the tools in the book– particularly breathing, grounding and sensing.
I’ve trained students to raise SAT and GRE scores 100-300 points just by regularizing their breath through the course of the test.
