Grade point is a method to evaluate academic performance, and the general calculation method of most universities in China is: grade point = score/10-5. Credit grade point = credit * grade point = credit * (score/10-5) (if the score is above 90 points, it will be calculated as 90 points). The average grade point average (GPA) of extended materials is the calculation unit to measure the quantity and quality of students' learning. Obtaining certain credits and GPA is the standard for graduation and degree, and various educational specifications and flexible teaching management systems are implemented.

There are many ways to calculate GPA. Take the standard 4.0 algorithm as an example: multiply the GPA of each course (including retaken courses) taken by students by the' credits' of the course, and then divide it by the total credits. The formula is as follows: GPA)= total (academic performance of each course * GPA of the corresponding course)/total credits.

In the day-to-day exams for graduate students in most colleges and universities, grade point is a necessary condition. Generally speaking, it is required that the GPA is above 2.8 to participate in the walk of graduate students, which is also an important reference index for scholarships, changing majors (double majors), studying abroad and exchange programs.
