Hi,John!
I apologize for not replying to you. I didn`t because I`m busy with studying.  I`m preparing to the exams. We`re having English,Russian and Maths exam. I think the most difficult exam is maths exam. But i do my best to prepare to it. It`s very important for this moment.
You know, I`m going to England after the exams to practice the English language. But I worry it`ll be difficult to adapt to Englishman`s life. But anyway, I`m sure it`ll be a wonderful experience in my life. People should develop their skills, and i think I`m not an exception. Could you be kind to tell me what difficulties i can expect in England?
With the best wishes, ...
