Stay well hydrated
Choose your beverages well, caffeine and sugar should be kept to a minimum. Since too much caffeine can make you jittery, try to drink moderate amounts: 400 to 450 mg per day, the equivalent of 2/2.5 cups, (500 to 625 ml). Better choices include water, fruit juice, milk, and anti-oxidant-rich green tea. The best liquid to drink before and during an exam is water. Water is essential as a body lubricant for various organs. Mucus that lubricates the digestive tract and the respiratory tract saliva, which makes it possible for us to, swallow the food, all contain water as an important component. So do not forget the elixir of life - water, during the exam days. Often fatigue and mild headaches is a sign that you are becoming dehydrated. If you do not consume enough water, your output of energy will drop. Carry a water bottle with you, and drink periodically throughout the day. Water also speeds up brain function.
