A recent study suggested that taking a bottle of water into the exam hall could help students improve their grades. According to the study those who brought drinks, 71 (especial) water, with them when sitting their exams performed up to 10 per cent better than those who did not. Comparing their exam results with their normal schoolwork grades, scientists then found that all those who 72 (bring) drinks with them got better grades 73 between 2 and 10 percent. It is unclear 74 drinking water improves exam results. But scientists say having enough water in our bodies and not feeling thirsty could have a 75 (help) effect on our brains. Drinking water may also cut 76 on anxiety, 77 has a bad effect on exam performances. Whatever the explanation, it is obvious that students should try hard to keep enough water in their bodies during exams. So next time, 78 you are going to have a big exam, try 79 (bring) a bottle of water with you. Who knows — it 80 help you pass the exam!
