Thank you for your email. It was nice to hear from you.
My teachers at school don't give me much homework, and I agree with you that it's good. I think it's important to have free time to relax and do other activities.
When I do my homework, I usually do it in the evening after dinner. It helps me to concentrate better when my mind is rested.
The most difficult subject for me is usually Maths. I find the problems challenging and require a lot of concentration.
Thank you again for your letter. I look forward to hearing from you soon.
Best regards,
