Just list your grades in all subjects in high school according to the percentage system. Write down how many points a, how many points b and so on. So you don't need to list your GPA, just make sure your high school grades are beautiful.
Just yourself. Calculate the A-D score of each subject. A is 4 points, B is 3 points, C is 2 points, D is 1 minute, and then add them up and divide them by the total credits.
Because most high schools in China don't calculate grades by credit, it is actually recommended to apply with the first one. At that time, I put my three-year high school grades in the first category to apply.
