        For most students, the time of exams is very stressful and difficult. Some people find exam time so bad

that they become ill, because they are afraid of failing; they are afraid of letting their parents and families down.

If exams are really making you ill or worried, don't hide your feelings. Talk to someone about it. If one person

doesn't help you, ask someone else.

       How to get through exams? Here are some top tips by educational psychologists (教育心理学家): 

       Ask a teacher or tutor about how to revise, and exam skills-how to work when you are in an exam.

       Take short rests during your time of work and revision. If your mind is tired, it will not remember well. 

       Plan your work: revise at times when you know you will work at your best.

       Get enough sleep, and eat healthy food.

       If you feel ill, talk to someone about your worries. But don't be too relaxed! Some stress over exams makes you work hard for them.

       If it upsets (沮丧) you to talk to your friends about an exam when it is finished, don't do it! In fact, don't

even think about the exam you have finished. What is done is done. You cannot change what you have written! 

        To this advice, we would add:

        If you are studying in the evening, don't go straight to bed afterwards. Your mind will still be "going round

and round"-thinking too much. Do something else, maybe walk or get exercise. Choose something that will relax

you, and make you think of other things.
