Nanjing University Xianlin Campus is going to take the postgraduate entrance examination. I won't go back at noon. Are there study rooms or empty classrooms in the school? Do I need to swipe my NTU card to go to the study room? The school has always had free classrooms to go to, and students who take the postgraduate entrance examination can go there to study, but it is good to find the right place, such as the second floor of Yifu Building. Because the teaching building often has classes, if it keeps occupying seats, it may be thrown away. Shaw Building, the teaching building of Nantah, does not need to be swiped. Only the library needs to swipe its card.
