According to the principle of "accurate calculation and presentation by grade" and the ranking percentile of "overall level score of disciplines", the top 70% of disciplines are published in 9 grades.
The top 2% (or 2%) is A+, 2% ~ 5% is A (excluding 2%, the same below), 5% ~ 10% is A-, 10% ~ 20% is B+, 20% ~ 30% is B, and 30% is B.
Matters needing attention
Generally speaking, taking business administration as an example, A+ majors can be called the top in the country (such as China Renmin University); A major with a discipline ranking can also be called first-class in China (such as Nankai University); It is very difficult to take the postgraduate entrance examination for A+ and A subjects. If these schools are targeted, the test for candidates is very great.
A- and B+ majors are already very competitive in China (such as Shandong University and Zhongnan University of Economics and Law), and the examination is not difficult.
