Can't simply say that Nanjing Hohai University graduate students do well in the exam, because good exams are relative:

1, compared with Nanjing University, it is certainly easy to take the exam, but it is not easy to take the exam compared with ordinary schools in the central and western regions.

2. Different people feel differently, because everyone's foundation and preparation are different. If the exam is well prepared, it will be easy, otherwise it will be difficult.
