假如你收到来自笔友jack的一封邮件,讲述自己考试成绩不理想非常苦恼.用英语写一封回信.要求,提建议

Dear Jack:
You have metioned that you feel anxious about your exam result.I am very sorry for that.However,you are supposed to cheer up!
First,nobody is perfect.There are many students whose marks are bad,but some students feel that it is nothing and never give up.As a saying goes:success is fail more a time that fail.
Socend,anxious can not sovel any problem.If you want to make study better,the only thing you should do is taking action and making difference.
Third,you are supposed to find what you are wrong and do not make a same mis take next time.If so,you will make good marks gradually and be master in study.
I hope that you can feel happy again!
Yours,
Li Hua
