I’m Wang Tao. Let me help you. Maybe every teenager likes playing computer games, but we shouldn’t play computer games too much. You’d better not stay up too late. You need to have enough sleeping time, so you can be energetic enough to study tomorrow. And you should concentrate more on your study because you are still a student. It’s our duty to study well. I hope you will be good at your study again soon.                                                                    

Another possible version:

   I’m Wang Tao. Let me help you.  First of all, please don’t worry your English too much. I think you failed the English test just because you played computer games too much and you stayed up too late. Don't do that again. If you can pay more attention on English,, you will get better grades soon. After all, your English was not bad before.     I hope you can get up early and do morning reading every day. Listen to the teacher carefully and make grammar notes. Also, do homework carefully , so you can make fewer mistakes. Believe yourself !
