Thank you for your letter. I am sorry I didn’t write sooner, but I’ve been very busy studying for my exams.
Your school has very interesting optional lessons. I wish I could take a sculpture class, but my school doesn’t offer one. But then, I don’t have much free time because I am always studying maths, my most difficult subject. I usually spend about four hours a night doing my homework. I don’t have much free time, but when I do, I enjoy playing computer games.
I’m sorry, but I have to go now. I have to write an essay for English class. Please write again soon.
