How to revise: 'If there is no learning without revision, there is no exam without rehearsal," writes Marie Murray.

"Understanding, learning, memorising and revising are but a part of the process. The crucial time is the three hours in which the student must convey what he or she knows in a clear, succinct, relevant and readable manner."

Revise with the exam in mind: There are specific formats to the questions asked in each subject and the number of questions to be attempted. Become familiar with this format so that when you sit down to the exam, you know exactly what style of paper to expect. Practice providing answers to a range of questions. You may want to use revision books.

When revising, time yourself, having worked out in advance how many minutes you can allocate to each question. In English, for example, prepare opening sentences for topics, note the important points then make those points paragraph by paragraph. Do this with a range of topics.

Don't worry if you cannot remember something - because you still have plenty of time to learn it and know it on the day of the exam.

The best approach to maths is to keep solving maths problems, making sure you understand what you are doing. Whatever the subject, you need to prepare by mentally going through the answers to various exam questions. By the time you sit down in the exam hall, you will feel comfortable with the challenge of thinking through a problem within a time limit. The same should apply to essays.

Practise writing fast, so that you can make the most of the exam time. Make a study plan. Allocate specific amounts of time to each subject. Study according to the same pattern every day. Scrutinise exam papers and draw up exam question lists. Review the curriculum, in case you've missed something.

At the end of each study session, ask yourself what you have learned. If your study has been so haphazard that you cannot verbally explain this to yourself or someone else, then you need to change the way you are studying.

Remember: IT'S NOT TOO LATE!!! Even if you think your approach to studying could have been better in the past, there is still time to change your ways now!

Don't panic, get organised. Notes, books, everything related to a subject must be in order. Murray suggests choosing a different coloured storage box for each subject. (This is a habit you should have established by now, but if not, understand that when your study materials are in chaos, your mind is too.)

Gather up all your essays and previous written assignments. Some of them may be worth memorising to form the basis of an exam answer.
