I write this letter to show you some advice about how to impore your study because I learn from that you have difficult on study. So here are my opinions.
Fristly,you should believe that nothing is impossible if you make up your mind to try, so you should do all you can to do to keep studying hard and never give up. Secondly,you should be good commmand of which style is useful to your study and try to ask others who are clever and warm—hearted for help, also I belive that they are willing to try their best to help you and you will learn more. Thirdly, you should finish you homework on time and learn to study by youself.As far as I am concerned that you always have a preference for playing computer games and watch TV after class. In my opinion, time should be made good use of to study the more you spend, the higher success you will get. So you'd better to spend more time on study as much as possible rather than do something meaningless. Finally, you shouldn't be too hard on yourself, after you finish your homework, you could go out with friends with a view to having a good rest and expressing your feelings.You should remember that there is no short way to success, so you should be much hard and don't lose heart when you fail the exaim.
I hope you will find these suggests helpful. On in this way can you improve your study and make progress.
Best wishes to you, come on!I would appreciate it if you could respond me early.
