AMERICAN class ranking is a complicated process. American classes count both exam scores and something called a “Grade Point Average” (GPA). Every semester, students receive grades for all of their subjects, “A” being the best and “F” being the worst. Each letter is worth a certain amount of points. In regular classes, an “A” is worth four points, a “B” is worth three points, and so on. In honors classes, where the content is harder and students have more homework than normal, each letter is increased in value by one point. In AP classes, which are university level, the letters are bumped up by two points. That’s why some students take honors and AP classes. At the end, the average of all your points is calculated, and the result is your GPA.
