Hi! My name is Anastasia. I used to be in math class but now I go to ordinary school. (Если раньше училась в математическом классе, то логично добавить, что сейчас учусь в обычной школе) 
My hobbies are connected with my favorite subjects. For example, I like Literature lessons and I read a lot. In addition to fiction (Помимо художественной литературы), I’m fond of reading biographies of famous people as well as literary analyses. Reading a book, I pay special attention to the personality of main characters. I'm especially interested in the man's inner world and in his consciousness. Among my favourite books are literary works which deal with various philosophies.
I like travelling as well. I have already visited several foreign countries such as France and Thailand as well as many cities of our country.
I have a pet. My dog's name is Naida. It (she) is 4 years old. My family and I adore it (her).
