Most of us think of tests as something designed specifically to trick us. The truth is, if you have studied and are totally prepared, then the test is actually an opportunity for you to show off how much you know.
The bigger and more important the exam is, the more we tend to suffer from anxiety. Exercise the morning before your exam. This will not only release built-up tension in your muscles, but it will also release “feel-good” endorphins that will put you in a better frame of mind.
