How do you calculate your GPA in high school?

To calculate your high school GPA, add together your grades on the 4.0 scale after converting them from letter grades, and divide the sum by the number of classes you are taking.

Additionally, many high schools use a secondary GPA system called a "weighted GPA system." The weighted GPA system adds extra weight to courses at the Honors, AP, and IB levels. The weighted GPA system can vary between school districts, so talk to your counselor about how your particular high school’s weighted GPA system works.
