During exams you are already under a lot of pressure so you need to relax in order to focus on doing as well as you can. Never compromise for anyone or anything. Your time is your time and nobody can give it back to you. If you think that you need one hour to finish a topic so take one and a half and complete it. So you will not have to stress over that and will manage a flexible schedule. No matter what try to be positive in every situation. It will take away half of your stress and give you a lot of confidence. Even if you are not prepared, don’t panic. Always get a plan B strategy and it will work. At the end of the day, your state of mind is the one thing which will keep you going through every situation. Before the day of exam try to cool yourself, revise only twice and have a deep sleep.
