what is a grade all
GPA (Grade Point Average) is a way of measuring academic achievement in high school. Itâs a numeric value that correlates with a studentâs grades. Each letter grade that a student earns is worth a certain number of grade points depending on how high it is and, in some cases, the level of the class where it was earned. The average of the grade points from all of a studentâs converted letter grades in high school makes up his or her final GPA.
