To calculate your high school GPA, use a four-point scale, awarding yourself the appropriate number of points for each grade earned. Then, divide the total number of points by the number of credits you've taken.
- Determine the number of points you've earned
Gather all your high school grades and award yourself four points for each A, three points for each B, two points for each C, one point for each D and no points for each F. Calculate the total points you've earned.
- Determine the number of credits you've completed
Calculate your total number of high school credits. Count each year-long course as one full credit and each semester-long course as a half-credit.
- Divide your points earned by your credits earned
Divide the total number of points you earned by your total number of high school credits. The answer equals your unweighted high school GPA.
