You will naturally feel nervous. Everybody is usually nervous before an exam or an important occasion. Whilst you’re in the waiting room (you should arrive 10 minutes early), take a few deep breaths through your nose and slowly release it through your mouth. This is a good exercise to calm you down. Do not go to your test feeling hungry. Make sure to eat a good meal a couple of hours before the test. Have something sweet like a chocolate bar as it is a medically proven fact that high sugar content food will boost your concentration levels.
