When revising, it is helpful to make a revision plan in advance and stick to it. To help your concentration, try to get enough sleep and exercise and limit your alcohol and caffeine intake.
If you find you are suffering from exam stress, you can consult the University Counselling Service.
They run workshops throughout the year including ones to help you cope with stress.
If the stress is severe you should contact your GP especially if you have been ill or had personal problems during the year.
If you are actually unable to take an exam at all because of illness or a personal issue such as bereavement, or if you have to leave an exam because you are taken ill, it is important to inform your department of the reason as soon as possible. Follow this up with another email with medical or other evidence as soon as you can. The regulations state that you should submit evidence within 3 working days of the exam.
Once you are in the examination room, try to remain calm and read through the questions carefully. Decide on the time to allot to each one and leave the one you are least confident about until last.
Look at the general exam regulations Regulation 10.2 which govern what goes on in the examination room.
If you fail a first year examination by getting a mark of less than 40%, you can usually resit the exam at the end of the summer vacation of the same year. Second year or final year students cannot normally resit a failed exam. In special circumstances, you might be able to resit exams the following summer without residence. This means that you take the whole year out of your studies. If this happens to you and you want to know all the implications, come and talk to an advisor in the Student Advice Centre.
