First of all, the review period of postgraduate entrance examination is very long, and different problems (learning and psychology) will appear at different stages. It is much better to help yourself establish a study group that can communicate and cheer up at any time than to fight alone. If your friends are diligent, there will be interaction and competition between you. I often fight with my friends when I take the postgraduate entrance examination. Who is more desperate than who studies 12 hours every day. And constantly exchange review methods, experience and information, and cheer each other up, which is of great help to my whole postgraduate entrance examination. Living together will make you realize this thing well.
Moreover, it doesn't matter if the students in the dormitory don't take the postgraduate entrance examination, but if the atmosphere in the dormitory is not conducive to your study, not only can you not have a good rest (the postgraduate entrance examination review is very tiring and requires high-quality rest to ensure the learning efficiency), but you will often be driven by them to do something unrelated to the postgraduate entrance examination. A very destructive state is not conducive to your focus on the postgraduate entrance examination. If the dormitory atmosphere is good, it's ok.
Finally, it is best to rent a house near the school, even in the school, which is the safest and can study without fear. Or if you have the ability to deal with your classmates, it is ok for several classmates to share a dormitory (there are many ways). I study hard in winter and live in a house far from school, and I am a woman. I often don't dare to study by myself until 1 1, so I have to return. But there is no problem around the school. It is safer for several people to study together. It would be better if it were a boy.
