Dear Andrew,  

Thank you for your letter. I'm glad to hear that you're well.

I have a lot of subjects at school too, but I think that Maths is the most difficult one. It requires pupils to be attentive, patient and scrupulous. We must always analyze tasks and learn a lot of symbols and formulas. It is so boring! I don't like this subject at all. As a rule, it takes me 2-3 hours to do my homework. Sometimes I have very little free time, but when I do have it, I usually listen to music or play computer games.

Well, I need to go now.

Keep in touch.

Best wishes,
