Calculation method: (the average score of all the exam subjects you have studied is -50)/ 10.

In other words, if the average score of all exams is below 75 when you graduate (note graduation), you won't get a degree certificate unless you brush some means, hehe.

If the questioner is worried about his low GPA, he should make up the courses with low GPA as soon as possible, because the further he goes, the lower his professional performance will be.

Good luck.
