Information
Practice as much as possible and find out how many minutes per question you have. Don’t worry if you don’t finish the exam though, accuracy is more important than speed so work quickly and carefully but don’t rush with wild guesses to catch up with the clock. Don’t be afraid to move on, you may find the more difficult questions are at the start of your evaluation so by not moving on you could be missing out on some easy questions and easy marks.
