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.
