EDUCATION IN RUSSIA

People in our country have the right for education. It is our Constitutional right. But it is not only a right, it is a duty, too. Every boy and every girl in Russia must go to school, that is, they must get a full secondary education. So, when they are 6 or 7 years old they begin to go to school. There are thousands of schools in Russia. There are schools of general education, where the pupils study Russian (or a native language ) , Literature, Mathematics, History, Biology, Music, Arts, Foreign Languages. There is also a number of specialised schools, where the pupils get deep knowledge of foreign languages, or Maths, or Physics.
After finishing 9 classes of secondary school young people can continue their education at different kinds of vocational or technical schools or colleges. They not only learn general subjects, but receive a speciality there. Having finished a secondary school, a technical school or a college young people can start working, or they may enter an Institute or a University. Professional training makes it easier to get higher education. As for high schools, there are a lot of them in our country. Some of them train teachers, others — doctors, engineers, architects, actors and so on. Many institutes have evening and extra-mural departments. That gives the students an opportunity to study at an institute without leaving
