1, it is the same whether the graduate students in Shenzhen University have a second interview or not, because they are all admitted according to the ranking after the second interview. If the second interview is difficult, just lower the score, which has little to do with admission or not, because if it is difficult, it is difficult for everyone, and if it is easy, it is easy for everyone. The difficulty will not affect the ranking after the second interview.
2. It is moderately difficult for Shenzhen University to take the postgraduate entrance examination. The difficulty is related to the city where the school is located and the reputation of the school, because the students are different. The key is to look at your own preparation, and it is not difficult to prepare for the exam.
