Homeschooling: High School GPA

How to figure GPA

First decide on a grading scale. I have two examples on this web page. Alter the numeric grade ranges to match the grade scale that you use.

Two Grading Scale Examples- Simple

A=94-100; B=86-93; C=77-85; D=70-76; F=below 70
A=90-100; B=80-89; C=70-79; D=60-69; F=below 60

Two Grading Scale Examples- Detailed and Shows Quality Points

The Grade and Credit Determine the GPA

For example, Geography will earn 1 credit. The student's final grade is B+. Using the grading scale above, the quality points (QP) for a 1 credit course that earned a grade of B+ is 3.33. PE is a 0.5 credit course. A grade of A earned for a 0.5 credit course gives a GPA of 2.00.

At the end of the year, total the grades and find the quality points for each grade/credit. Add the QP and divide the sum with the number of credits earned.

In the example above, the green column shows the QP's that were earned for each course. The QP's are added and they total 21.33. To get the cumulative GPA, divide the total (21.33 in the example) by the number of credits that were earned (6 in the example). This yields a GPA (grade point average) of 3.5.
