Today our gymnasium consists of two buildings: the old and modern ones. The old building is considered to be architecture monuments of the 19th century. I must say that two years ago it was repaired inside and now some classrooms and a hall on the first floor look quite modern. On the ground floor there are two workshop for boys, a home enconomics room for girls and three classes which need repairing.

The modern buildings is a three-storied one. One the ground floor there are two cloak-rooms, a canteen, where pupils have meals: breakfast and lunch. Chemistry and Biology laboratories equipped with different flasks, test tubes, stuffed animals are also on the ground floor. I can't help saying about the flowers and two little fountains which decorate the central part. When you enter the school you find yourself in a garden. It's wonderful.

The first floor is occupied by classes studying various subjects: Physics, English, Music and History. There is Teachr's Room Headmister's study and an Assembly Hall is large and beautiful. Different festivals, concerts, perform,ances and meetings are held there.

If you go father up to the second floor you will see classrooms where senior pupils study Maths, Literature Russian and Belorussian languages. Besides we also have two Information Technology room where basik computer skills are taught and a library where there is fiction, newspapers and magazines.

As you see our gymnasium is well-equipped with necessary devices, literature and tools. All teachers working at our school are highly qualified. They teach us to solve different problems, write compositions, acquaint us with certain specific theories and ideas. They share their knowledge and experience with us. We appreciate it and respond with love.
