Education in Russia.

Our educational system is not very complex. It is divided into three stages: preschool education, secondary education and higher education. Each of them has its own peculiarities.
The preschool education is provided by nursery schools and it depends upon the parents to send their children or not. There children learn the fundamentals of reading, writing, counting.
There are different types of secondary schools: general secondary, technical schools, and vocational schools.
Every boy or girl must get secondary education. They go to school at the age of six or seven and must stay there until they are 14-17 years old. At schools pupils study academic subjects, such as Russian, Literature, Mathematics, History, Biology, a foreign language and other.
Higher education in our country is available to those having secondary education who have passed entrance examinations. Most colleges, universities and institutes are state ones, but there are also private colleges. They train specialists in different branches of science and technology.
Most higher schools have their own hostels and living and recreation complexes for students.
Our educational system is in the process of perfection to meet the requirements of our developing economy.
