Average GPA (Grade Point Average) refers to the typical academic performance score of a student or group of students, calculated on a scale such as 4.0. In the United States, the average high school GPA is usually around 3.0 (a B average), while college averages often range between 2.7–3.3, depending on the institution and major. GPA is calculated by assigning point values to letter grades (A = 4.0, B = 3.0, etc.) and averaging them across courses.
