Read the passage and choose the best answers to the following questions.
British teenagers sit up to 70 exams and tests before they reach their GCSEs (The General Certificate of Secondary Education). But there are ways to ease the stress at exam time.
What a student eats and drinks in the run-up to exams can influence how clearly they think and how happy they feel. A balanced diet with lots of fruit and vegetables, fish and complex carbohydrates will help them concentrate and think clearly. Too much high-fat, high-sugar and high-caffeine food and drink can make studying harder.
Sleeping well and for long enough to feel rested, around six to eight hours for most people, will help thinking and concentration. Students should allow half an hour or so to wind down between studying, watching TV or using a computer and going to bed to help them get a good night's sleep. Regular exercise also helps them sleep better. Cramming all night before an exam is usually a bad idea.
Parents should be flexible around exam time. When a child is revising all day, don't worry about household jobs that are left undone or untidy bedrooms. If they're a bit moody they should stay calm. They can help a child to revise by making sure they have somewhere comfortable to study.
Students should remind themselves that feeling nervous is normal. Nervousness is a typical reaction to exams. All students will feel it. The key is to put these nerves to positive use. Being reminded of what they do know and the time they have put into study can help them feel confident that they can reach their potential.
