1.) Take it again. Just by taking the test you have gained important experience in what it’s like. The normal TOEFL test-taker improves his/her score significantly from the first to the second attempt. Additional attempts also usually result in increased scores.
2.) Get a good night’s sleep. The normal person needs 7-9 hours of sleep (individual needs may vary). If you have trouble sleeping, try to do some light exercise, stretching, and relaxation breathing (although exercise is not recommended right before bed).
3.) Wake up early. Take a long walk or jog. Also stretch and focus on deep, relaxing breathing.
4.) Try to become comfortable but alert. The test takes around four hours. Make sure to have a complete, healthy breakfast the morning of the test, but don’t overeat. Also drink a couple glasses of water (you want to be hydrated – your brain will perform better – but you don’t want to have to go to the bathroom during the test!).
Stick to your normal habits. If you normally drink one cup of coffee in the morning, for example, then try to have one only cup of coffee before you take the test (and not more). If you are a smoker who normally smokes early in the morning, it’s okay to smoke before the test. Actually, some evidence suggests that smoking can improve short-term test-taking ability, since nicotine is a stimulant. Don’t try to quit smoking in the same month that you take the test. (However, you should quit smoking!)
5.) Do you suffer from any form of test anxiety? Several recent studies have shown that if nervous test-takers sit down just before a test and write down all the reasons why the test causes them anxiety, they will perform significantly better on the test and actually feel less stressed. This exercise is easy and usually only takes about ten minutes. Why not arrive to the test center early and do this?
