I learned that your website is a famous website that can help students with their problems regarding education. I have a friend. He is a hard-worker and always listen to teachers during class. He can also answer the teachers' questions correctly. He can also finish his homework after class easily. He seems to have no problem studying. However, he always gets nervous during exams. So he doesn't have good grade. He doesn't know what to do. Can you give him some advice?

我听说你们网站是一个有名的能帮助学生学习上问题的网站。我有一个朋友。他很努力而且上课一直认真听讲。他也能正确回答老师问题。他还能轻松的完成回家作业。他看上去没有学习问题。但是，他考试的时候就紧张。所以他成绩不理想。他不知道该怎么做。你能给他一些建议嘛？
