Subject: My english score

Dear Miri,

Hi Miri! It's me, your good friend Zack. How are you? I hope you're doing well. I'm fine by the way. I just want to tell you that I got C on my English test on school yesterday. I think I have to study more hard to fix my score on the next on coming test. I just wonder if you could help me to study, since I know that you're great in english lesson. Just let me know, if you have a free time to do it for me. Thanks anyway.

Yours truly,
Zack Brown.
