Have a healthy and nutritious breakfast. Keep away from heavy saturated foods such as Margarine and foods with high sugar content. Try to eat a balance meal of eggs, toast, or cereal and some fruit. Make sure you are refreshed by drinking a glass of milk, juice or water, (make sure you don't drink them together, or you will be sick for the exam!). You need to ensure you have had the correct foods that will keep your energy and body functioning until the exam is over. Don't overeat, being too full will mean your stomach will hurt and you may feel nervous. Dark chocolate helps for brain boosting as berries do.
