Do you want to improve the way you study? Do you feel nervous before a test? Many students say that a lack of concentration (注意力) is their biggest problem. It seriously affects their ability to study, so do their test results.

If so, use these tips to help you.

Study Techniques

l You should always study in the same place. You shouldn’t sit in a position that you use for another purpose. For example, when you sit on a sofa to study, your brain will think it is time to relax. Don’t watch TV while you are studying. Experts warn that your concentration may be reduced by 50 percent if you attempt to study in this way. Always try to have a white wall in front of you, so there is nothing to distract (make less concentrated) you. Before sitting down to study, gather together all the equipment you need. Apart from your textbooks, pens, pencils and knives, make sure you have a dictionary. If your study desk or table is needed when you are not studying, store all your equipment in a box beside it.

l Your eyes will become tired if you try to read a text which is on a flat surface. Position your book at an angle of 30 degrees.

l Be realistic and don’t try to complete too much in one study period. Finish one thing before beginning another. If you need a break, get up and walk around for a few minutes, but try not to telephone a friend or have something to eat.

Test-taking Skills

l All your hard work will be for nothing if you are too nervous to take your test. Getting plenty of

rest is very important. This means do not study all night before your test! It is a better idea to have a long-term study plan. Try to make a timetable for your study which lasts for a few months.

l Exercise is a great way to reduce pressure. Doing some form of exercise every day will also

improve your concentration. Eat healthy food too.

l When you arrive in the examination room, find your seat and sit down. Breathe slowly and

deeply. Check the time on the clock during the test, but not too often. Above all, take no notice of everyone else and give the test paper your undivided attention.
