Being successful in an exam is not just about studying hard and knowing the subject inside out. 1

Research has shown that the calmer the mind, the better its ability to register and remember information. 2 When the mind is relaxed, it is in the "state of alpha", where your brain waves are at about seven to fourteen cycles per second, the most helpful state for studying.

Choose a quiet place for studying and have everything handy that you need: books, pens, something to drink. 3 In this case, you can see yourself being congratulated by your family, friends and teachers. Enjoy the experience. And now you should be completely charged up and ready to absorb and keep important information.

4 It is a good idea to make a list of all the important things you have to learn, in order of importance, and estimate how much time you need for each one. Add it all up and compare this with how much time you have available. This will tell you if you have time to read slowly and carefully, or if you can only skim; also it will show you how many times you can afford to look over the same information.

Because stress can have a negative effect on your memory, it’s important to stay calm during tests. 5 Breathing exercises during the examination, for example, can be extremely effective in helping you relax and reverse your stress response: just take deep breaths, and let the stress coe out when you exhale(呼气).

A. Learn to both read between lines and skim.

B. Ensure that you sleep and eat well before a test.

C. Relax your body and mind and imagine the day of the results.

D. There are some stress relief techniques that can help to calm you down.

E. There are other things that you can do to help ensure you get good grades.

F. Every time you sit down to study, give yourself five minutes to calm your mind.

G. Depending on what you want to study, and how much you have to cover, plan your time.
