The first gradient (subject evaluation is A and above): Tsinghua, Peking University, Xi Jiaotong University, Tianjin University, Dalian University of Technology, Beihang University, etc.

Compared with the universities with the first gradient, the universities with the second gradient may have slightly worse professional strength, but there are also some established 985 universities, so the competitive pressure of the second gradient is not less difficult than that of the universities with the upper gradient. At the same time, comprehensive universities such as Sun Yat-sen University and Southeast University may be slightly worse in their majors, but their cost performance is still very high.

The third gradient (C-class universities with discipline evaluation level): Yanshan University, Xiangtan University, Ningbo University, Inner Mongolia University of Technology, Kunming University of Science and Technology, etc.
