英语作文我的朋友要上高中了，但是她好紧张，有没有什么办法能让她不紧张

I've heard that you will take an exam tomorrow, and I hope you can get a good grade. Please make sure you do not make yourself nervous. Being nervous is absolutely useless to you. You can not be in concentration because of that. And I am afraid you will not be well during the exam if you are too nervous. So just relax! Believe that you are already in the best condition. And remember to keep a positive attitude which means you should enjoy your time. Do something that make you relaxed and happy before the exam, so you are not going to be too nervous. And also, you are supposed to get enough sleep at the night before the exam. Trust yourself.Good luck!
Best wishes
