Did you know that recent research has shown that just writing about all your worries and anxiety concerning a test, right before the test starts, actually significantly reduces stress and increases test scores.
Our advice: Get to the test center early (this is a good idea anyway) and bring some extra paper to write about why the test is stressing you out. Researchers suggest having about ten minutes to write.
This technique can be used for ANY stressful or high-pressure situation, if you just have the time just before to do this.
