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).
Generally, different subjects have different credits. There are four credits in Advanced Mathematics and six credits in Circuit Theory. The credit of the subject is the weight of the subject. So the weighted score is the subject score multiplied by the credit value of the subject, and the weighted average score is the sum of the weighted scores of all subjects divided by the total credit.
The calculation of weighted average score is similar to GPA algorithm. t3
