1. Give yourself enough time to study
Don't leave it until the last minute. While some students do seem to thrive on last-minute 'cramming', it's widely accepted that for most of us, this is not the best way to approach an exam. Set out a timetable for your study. Write down how many exams you have and the days on which you have to sit them. Then organize your study accordingly. You may want to give some exams more study time than others, so find a balance that you feel comfortable with.
