The credit grade point is the score of the course you have studied, and the thesis is the content you have learned in the whole learning stage. Grade point is a method to evaluate academic performance, which is commonly used in most universities in China: grade point = score/10-5, credit grade point = credit * grade point = credit * (score/10-5) (if the score is above 90, it will be calculated as 90). Some schools adopt different calculation methods, namely, subsection grade point method, which emphasizes grading grade points according to scores.

As follows:

4-3*( 100-f)^2/ 1600。 Average GPA: (course credit 1 * GPA+ course credit 2 * GPA+ course credit n* GPA)/ (course credit 1+ course credit 2+ course credit n) GPA system is one of the important supporting measures to implement the credit system. Since 1985 China began to advocate the implementation of the credit system, people have discussed and studied the credit system more, lacking the discussion of the grade point system, thus affecting 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.
