London, April 18 (IANS) Simply a glass of water could be the key to exam success, say British researchers.
Students who took a drink into the exam hall did up to 10 percent better than those who did not - the difference between a grade, the Daily Mail reported Wednesday.
Although it is unclear why a drink should help, one theory is that information flows more freely between brain cells when they are well hydrated.
Researchers said that drinking water may also calm nerves, while those who became thirsty during test time could be more easily distracted.
The study, which looked at hundreds of university students, compared whether they took a drink - such as water, coffee or cola - into the exam with their final marks.
The students' overall academic ability was then factored in, to ensure that the results were not skewed by the possibility that smarter students are also more thirsty.
The study was presented at the annual conference of the British Psychological Society.

I understand precisely what is being discussed in this article. Pausing to have a drink probably gives students the time to collect their thoughts and to express themselves better. However I had to laugh since I have the experience of teaching in a Private College. As is the norm in India these "Institutions" exist solely for the purpose of making money. One of the incentives offered to students there was the facility of cheating during Exams - for a fee of course. The modus operandi was that those students who had paid in advance would be offered written notes - taken from textbooks in the hour following the start of the Exam - by the Water Boy who served the students at their seats.
