Dear Ben,
... I'm happy to hear from you again.

You asked me some questions ...
I'm glad to answer them. I'm going to have my exams in June, so I'm very nervous about it. I have chosen ... because in Russia students must choose these subjects. ... I have chosen English as I'm good at it and History because I'm very interested in this subject. In summer I'm going to go to the Black sea with my parents after my passing exams.
