Average credit score = each science score * test score/total credit. Credit grade point: each subject can get credit as long as it passes the exam, those who pass the exam can get credit, and those who fail have no credit. The total average credit grade point is equal to the credits of each subject multiplied by the credits obtained from the examination (59 points and below are no points, 60~64 points are 1 point, 65~69 points are 1.5 points, and 70 ~ 75 points are 70 points). That is, the average credit score = each science score * test score/total credits. In addition to attending classes, you can also get extra points by participating in some major competitions.
