Sleep:

Why study all night only to find out your head isn't working and you are making sloppy mistakes on the exam? Nobody is going to ask you how much you studied the night before, they are going to look at your answer sheet. So make sure you don't cram before the exam.

There have been several researches on how sleeping the night before helps us perform better in exams. One study found that students who got a whole night's sleep before the exam did 25% better in a multiple choice exam than students who didn't. Another study found that students who slept well the night before their math exam did better than those who didn't. So do not sleep less than you usually do the night before the exam.

Eat:

Skipping breakfast before an exam is not a good idea, you don't want to think about food while you are writing do you? A study among secondary students in Durham showed that students who drink enough water and healthy food such as fish oil or healthy carbohydrates do better in exams. So eat healthy food. Avoid rich food, sugary food, junk/fast food and other heavy food that are hard to digest.

Meditate:

If you know how to meditate, do not miss your meditation before the exam. Some top students we know actually increase the number of meditations they do per day before the exam, this helps them get by with less sleep and remain calm and alert.

Organize Your Things:

Organize all the things you will need the night before the exam the night. In that way you won't spend time rushing in the morning.

Be at the Exam Hall Early:

Take your seat at least fifteen minutes before the exam starts. Meditate for five minutes. Repeat the autosuggestion: I remember everything I read. Everything will come spontaneously when I sit down to write.
