Ответьте на вопросы про колледж.
My college I study at the college of communication, information technology and management. Our college gives secondary-professional education. There is a day time, an evening or correspondence departments at our college. The complete course of study lasts three years. About 8 hundreds of students study at the college. We study the humanities and the technical subjects and also have seminars and tutorials in these subjects. The college is located on Chervishevskiy Trakt Street,13. It occupies a three-storeyed building. On the ground floor there is a gym, a canteen, a cloak room and some classrooms. On the first floor there is a big and beautiful assembly hall and different well- equipped classrooms. On the second floor there are some computer rooms with the modern equipment. Students can live in the students hostels, which are located near the main building. The college gives students plenty of opportunities to develop themselves: besides getting professional knowledge we can participate in extracurricular activities, to attend different clubs.
