短文改错

Thanks for your letter. You are describing a common problem experiencing by students all over China. What you already know, the competition to get into a good university or college is very fierce, and that by turn means a heavy study load for students. I know that this can feel like terrible burden at times, but my advices to you is to keep on studying as your hard work will pay for in the end.

In the meanwhile, do you best to relax. Proper rest and relaxation are extreme important. Although I know that you are very busy, but yet I want you to try to set some time aside after class and at the weekends such that you can unwind properly.
