Our school is a fine four-storeyеd building. There are many classrooms and specialized rooms for studying different subjects in it.

The pupils study Mathematics, Physics, Chemistry, Ukrainian, Russian, Chemistry, Physics and Biology are taught in well equipped science rooms. There is a good equipment for laboratory experiments there. At the lessons we often carry out different experiments.

Mathematics is taught in the science rooms on the third floor. There is a special room equipped with calculators and computers.

There is the Assembly Hall on the first floor of our school. We usually gather there to mark holidays.

On the second floor there is a gym. We like our gym, and we like to spend there the breaks. During the breaks we usually played there basketball or volley-ball.

The dining-room and the canteen are on the ground floor. On the ground floor there is a workshop too. There we are taught to use some tools and machines.
