1 What is GPA?
GPA stands for Grade Point Average. It is a numerical measure that represents your academic performance in high school or college. GPA is calculated by converting your letter grades into grade points and averaging them based on the credit hours of each course.
Colleges, universities, and sometimes employers use GPA to assess students fairly, predict academic success, and make admission or award decisions.
