Our school. Our school is a specialist school for creative children and we have unusual subjects like History of Music, Art or theatre and Entry course to Russian art. We learn a lot of new and exciting information which broadens your horizons. Students go to school by public transport (often by underground) because the school is located in the centre of Moscow. For this reason, classes start at 9am. Lessons are shorter than usual ones: they last forty minutes. We leave school at 15:10pm. We have no strict rules and everybody feels comfortable. For example, we have never worn uniforms. And also if you participate in any cultural event like concerts, you are allowed to skip classes. The most important part of our schedule is music education. Many students learn to play the piano. We have our own musical school. It is open for everyone who wants to study. Even if you are 17 and you have never tried playing the piano! We also have dancing and ballet classes. Unfortunately, each school has its drawbacks. Our small library, canteen and concert hall seem to be unsolvable problems. But we do not get discouraged because we really love our small and cozy school.
