I'm writing this letter without help of anything. I hope, what you can help me correct my mistakes :)

Hello, my name is Семён. I'm from Russia, Saint-Petersburg. I study in National Mineral-Resourses University on 4th course. I will mining engineer. Five days at week I go to the gym. Also I go to swim on Fridays. I like it! At free time I learn English, read books and make me better.

Thank's for you time.
