Share the postgraduate entrance examination with students of the opposite sex and with couples who are not classmates?

Why can't I share a room with a classmate of the same sex? Actually, this is the best choice. Take a good postgraduate entrance examination and try to avoid all interference except study.

If you share a room with the opposite sex, you may be distracted. Even sworn brothers, some people will gossip. Although gossip is boring, it is always annoying to listen and to study for postgraduate entrance examination.

Sharing a room with a non-classmate couple? Tired of learning and stimulated by dog food
