1, universities generally calculate their grades according to credits and credit scores, that is to say, although he calculates his grades in various subjects according to the percentage system during the exam, he finally shows them in the form of credit scores when measuring whether his grades are excellent or not. Generally speaking, GPA above 2.8 is better. Generally speaking, it is divided into five grade points, which means that the highest grade point for a semester or the whole school year is 5.0, and you can get all subjects 100. If the average score of each subject is 90, the credit is 4.0, and if the score is 80, the credit is 3.0.

2, because this credit grade point is not only related to the score of each specific exam, but also related to whether each course is a compulsory elective course or a compulsory course, and also related to the hours. Some courses have three credits, maybe his credits are higher, while some courses have only 0.5 credits. Even if you get 100, his credit score is not very high. Therefore, there is a specific formula for calculating the credit score. In general, we can default to an average score of 80 for 3.0. In this case, if the GPA is 2.8, it will be almost 80 points, so it is not very bad.
