The general calculation method of most universities in China is: GPA = score/10-5, credit GPA = credit * GPA = credit * (score/10-5) (if the score is above 90, it will be calculated as 90).

The grade point system is one of the important supporting measures to implement the credit system. Since 1985 began to advocate the implementation of the credit system in China, there have been many discussions and studies on the credit system, which has affected the smooth implementation of the credit system. This paper analyzes and studies many problems existing in the process of adopting the grade point system in domestic universities, and puts forward corresponding countermeasures on the basis of comparing with the grade point system implemented in American universities.

There are four scoring methods for extended data: arithmetic average score, weighted average score, credit rating point and average credit rating point.

Arithmetic average is to add up the scores of all subjects and divide them by the number of subjects;

The weighted average score is the sum of the scores of each course multiplied by the corresponding credits of the subject, and then divided by the average of the total credits;

The sum of the credits is the sum of the credits of each course multiplied by the corresponding credits;

The average GPA is the sum of credits in each course multiplied by the corresponding GPA divided by the total credits, that is, the sum of credit GPA divided by the total credits.

Among the four grading methods, China mainly calculates the weighted average score of credits, while foreign countries adopt the five-point system, mainly using the average grade point. The sum of GPA and GPA has the same effect.
