I know the exam is coming soon and you are quite worried about it. I want to give you some advise to help you to overcome the anxious. First of all, you need to calm down, tell yourself you are the best and you will pass the exam easily. Secondly, you should take care of yourself. Eat balanced diet and do some exercise to help you to relax. Finally, revise for your exam carefully, make sure you don't forget the little things that can improve your score.
Good luck with your exam!
