Dear ......Thank you for your letter. I was very glad to hear from you. School exams are very difficult and take a lot of time. In your letter you ask me about the most difficult subject for me, there are physics, math and chemistry, because these subjects are very tricky and I don't understand them. As for my English exam I prepare ten topics about my life.Sorry but I have to go now, by mum asks me to help her.Best wishes.Твое имя
