Grade Point Average is an index that scores test scores and calculates them together with credits to measure students' learning quality. Different schools use different calculation methods, so their grades are different. For example, common calculation methods:

Grade point = score/10-5, credit grade point = credit * grade point = credit * (score/10-5) (more than 90 points are calculated as 90 points).

In order to make GPA accurately evaluate students' learning situation, the Academic Affairs Office also stipulates that all courses roughly conform to the normal distribution, and once again emphasizes that the excellent rate (above 85 points) should not exceed 20% in principle, and the unqualified rate (below 60 points) is 1%- 10%.

Before entering grades, the academic staff of each department should check the distribution of grades. If they deviate too far, they should submit their scores to the dean/director in charge of teaching in the department and ask the teachers to fine-tune the scores. In addition, as a compulsory course for all students, the scores of general elective courses and public elective courses should be more in line with the distribution given by the school, which is particularly important for the fairness of GPA evaluation.
