Renting a house for postgraduate entrance examination is not a necessary condition. You can decide whether you need to rent a house according to your economic ability and surrounding environment. First, the cost of renting a house is much higher than that of accommodation. At the same time, college students may encounter black intermediaries when renting a house outside, so they need to consider the economic level and be careful to be cheated; Secondly, considering the efficiency of preparing for the exam at school, if all the friends in the dormitory plan to take the postgraduate entrance examination, the dormitory has a strong learning atmosphere, which is conducive to preparing for the exam. You can also prepare for the exam in the library and study room. If their environment is not suitable for preparing for the exam, such as roommates playing games and talking on the phone in the dormitory, or the school hardware facilities are not good and there is no favorable environment for preparing for the exam, renting a house outside is a better choice. Wish the postgraduate entrance examination go smoothly!
