My number one rule when taking exams is: Never think too much.
Number two : Breath , make sure u have water.
Number three: Never talk about the answers after if ur feeling 'meh' about a question it might make u feel even worse if you think ur wrong, hence affecting your other exams.
Number 4: Confidence. Im sure if your revising hard enough you will get your grades.
