求助亚利桑那州立大学的GPA计算

求助各位：这个亚利桑那州立大学的GPA计算方法什么意思：
100-percent (100-point) system  
undergraduate grade/mark average (GPA)
In the 100-Percent (100-point) system, the undergraduate GPA is determined by adding all earned marks for all semesters, dividing that number by the total number of points possible and multiplying by 100.
是算算术平均分吗？

对 就是算术平均分 中国的学生都是这个分数 xx/100
