traditional British school . Well, I went to a traditional British public school . I left it four years ago. The school is in the city. It has about 700 students, and it's mostly a boarding school. There are lots of facilities for sport - tennis courts, a swimming pool. There are also good science laboratories and lots of computers. The classes are small, so if you fall behind with you work the teacher will help you with it. It may have changed now, but we did a lot of subjects and we even had lessons on Saturday mornings! We had some free afternoons when we could be together. They have us lots of homework and we had tests all the time. I remember that afterschool clubs were quite popular. I was in a drama club- we once put on a performance of Hamlet. There lots of rules and discipline was strict. We could only go out of the school at certain times, and we had to wear a uniform. перевод на русский пожалуйста
