Dear, Ben
Thank you for your letter. I'm sorry I haven't written for so long, because I've been busy with my study.
In your last letter you asked me about my upcoming exams. Well, my first exam is going to take place in May and my last one in June. Besides Russian and Math - exams that everyone passes, I chose History and English as I'm very good at them. As for my summer holidays, I'm planning to go to the country with my family.
Well, that's all my news. I've got a lot of homework to do. Hope to hear from you soon.
Best Wishes,
[твое имя]
