Many students put off studying, thinking that they will "get around to it" later. Often, that time never comes, and they panic when an exam is announced. You can overcome this problem by studying regularly. Review your class notes each night. If there is anything you don't understand, ask your teacher for help. Do your homework. Even if you are not assigned homework, read the text and answer some of the questions in it anyway. On the day of the test, go over the information once more. If you study daily, you are less likely to feel nervous before a test.
If you take care of your body, your mind also will be healthy and strong. Exercising makes you feel better and think more clearly. Try working out for a week or two before the exam. The night before the exam, get to bed at a decent hour. That way, your mind will be alert for the test.
Eating a meal before the test will help you concentrate and focus. Skip sugary or greasy foods that do little for your health and make you feel sluggish. Eat a healthy breakfast, such as fruit, whole-wheat toast, cereal or oatmeal. Although caffeinated beverages can help you wake up, they also make you more jittery. Stick with water or juice instead. If the test isn't until later in the day, bring a snack -- pretzels, crackers, fruit, vegetables -- so you can refuel.
No matter how well you prepared, it's difficult to know how you will feel when the test is in front of you. If panic strikes, close your eyes, breathe deeply and slowly. Repeat the word "relax" in your mind, or choose another word that makes you feel peaceful. Remember, you have studied hard and should expect a good grade. If you can't remember the answer to a question, don't allow anxiety to creep over you. Skip that question and go to another one. You can come back and try again later.
