I think it is better to live on a student campus. The campus is а paradise for students. There is everything for work and leisure of teenagers. There students can communicate with their mate rooms and with neighbours. The campus has classrooms, research classes, accommodation for students, the library and the reading hall with computers. In a word, everything there motivates students for learning. More over the campus for students is much more comfortable than the flat because it has a dining room, but when living in an apartment you have to cook for yourself or to have supper in an expensive cafe. Usually the campus is not far from the university. So the students will not be late, and they will have more time for themselves. While living on a campus, you can participate in interesting events organized on the campus. Students can enjoy the entertainments and attractions when living on a campus. Besides, there is a TV, a shower, toilets, a cafe, a store and a laundry. Thus, I believe that life on a campus is easier and more interesting than in an apartment.
