Dear Mary,
Thank you for your letter. I received it yesterday.
 I'm proud of you for getting such good marks! Great you are!
As for me, I usually get good marks like 4 and 5. To tell you the truth, I worry about my school marks because if I have bad marks, it will spoil my certificate, you know...I definitely worry about my future exams, I think it is the main part of our education and everyone should prepare for them and pass successful!
Now, its my turn to ask you some questions.
What are your summer plans? Will you come to see me? How do you prepare for your exams?
Thats all for now.
Write soon.
Best wishes,
