Believe it or not, a touch of nervousness can sharpen your mind, allowing you to perform more quickly. This is because under stress, the body can release(释放) something useful, which prepares it for something important that will happen.
However, too much anxiety can result in sleeplessness, loss of appetite before tests and poor performance. Some people might feel shaky, hot or even sick.
Those who have prepared poorly for a test or have had negative experiences (in) taking tests may also experience text anxiety. If you are likely to have a case of test anxiety, don’t panic. By recognizing the problem, you are taking the first step towards overcoming it. Talk to yourself using positive language. Make it a habit to replace each negative thought with a logical(合理的) reason. For example, “I’ve studied hard and I know the material, so I’m ready to do the best I can.” Another thing you can do is to learn to accept mistakes. In fact, they can be valuable learning opportunities.
Last but not least, start test preparation early—three to five days ahead of the test. After all, good study habits and skills—for example, time management and note-taking—will give you that you are in control.
