My school

We begin our school study at the age of 6 and at the age of 17 we finish it. When at school we have our lessons 5 days a week. The classes start at 8:30 a.m. (as I live not far from my school, so I have no excuse to be late for classes) and at 3 p. m. the lessons are over.

My school has got three floors. On the first floor there is a cloak-room, a dining room and a library. The library is well stocked with books from the reading list of recommended books for pupils. Opposite the library, there is a school canteen where pupils can eat during the breaks.

Our classrooms are on the second and the third floors. Most of the classrooms are very much alike. They are all light, airy, with flowers on the window sills, with portraits of outstanding people on the walls and with charts and maps near the blackboard.

Nevertheless, there are many specialized rooms for studying different subjects. Chemistry, Physics and Biology are taught in well-equipped science rooms. There are also schemes and tables on the walls. A special room for computer studying is equipped with computers. There are specialized linguistic laboratories for studying foreign languages. Besides, pupils have lessons in workshops, having practice in various crafts.

We have our classes of physical training in either our gymnasium or on the sport ground, situated behind the school building. On the first floor, there is an assembly hall where parties meetings are held.
