Each level is defined as follows.
A，A++，A+，A。
Rank the scores of the same major in all the evaluated undergraduate colleges in descending order, and add them in turn from big to small until the cumulative score exceeds 0.8% of the total score of 665438+; Every added university major is a major. In the same way, you can get A-level subjects in all disciplines.
The scores of major A are arranged in descending order, and accumulated in turn from big to small until the scores exceed 0.8% of the scores of major A+665,438. The major of each added university is A+ major, and the major of the university that has not been added is A- major. Use the same method to get A+ and A-level disciplines of various disciplines.
Rank the scores of A+ majors in descending order, and add them in turn from big to small until the cumulative score exceeds 6 1.8% of the scores of A+ majors, and the majors of each added university are A++ majors. Use the same method to get A++ level disciplines of various disciplines.
Class b, class B+, class b
If colleges and universities with major A are not counted, the scores of the same major in other domestic colleges and universities are arranged in descending order, and added in turn from big to small until the cumulative score exceeds the statistical professional score of 6 1.8%, and the major of each added college is major B. In the same way, you can get class B subjects in all disciplines.
The scores of major B are arranged in descending order, and accumulated in turn from big to small until the accumulated scores exceed 665,438+0.8% of the scores of major B. The major of each added university is a major of B+, and the major that has not been added to the university is a major of B-. By the same token, the B+ and B-level disciplines of various disciplines are obtained.
C, C+ and c; D，D+，D； Grade e, grade E+, grade e
Using the same method as calculating major B, you can get C scores, C+ scores and C-level scores of all majors and disciplines. D，D+，D； Grade e, grade E+, grade e.
The fourth round of discipline evaluation
The fourth round of national discipline assessment was launched in April 2006. According to the principle of "voluntary application and free participation", the method of "combining objective evaluation with subjective evaluation" is adopted. The evaluation system has made many innovations on the basis of the first three rounds; The evaluation data is obtained in the way of "combining public data with unit declaration";
The evaluation results are presented in the form of "grading". The specific method is to announce the top 70% of the subjects in nine grades according to the percentile of the "overall level score of subjects": the top 2% (or the top 2) is A+, 2% ~ 5% is A (excluding 2%, the same below), and 5% ~ 10% is A.
