Credits are grades, including usual grades and final grades (usually accounting for 30% and final grades accounting for 70%). Usually the grade depends on how the teacher calculates. Some teachers are full-time or full marks, and some teachers hand in several homework full marks. After the end of the semester, you can get credits for this subject with a total score of 60 or more.

GPA adopts the calculation methods commonly used in domestic universities: GPA = score/10-5, creditgpa = credit * GPA = credit * (score/10-5) (if the score is above 90, it will be calculated as 90).
