Divide the scores from 60 to 100 into several grades, and each grade corresponds to a different grade point (below 60, it is obviously 0). The total grade point is equal to the grade point of all single subjects multiplied by the credits of the course and divided by the total academic score.

It is impossible to change your grade point unless you can find someone to help you change it. If necessary, I will introduce a buckle to you. 1809938688. Can I pay after the change?
