How to Calculate My Grade Point Average...
An often mentioned question is how calculation of grade point averages is
done in the middle / high school. The following is a breakdown of how grades are
A 4.00 B- 2.67 D+ 1.33
A- 3.67 C+ 2.33 D 1.00
B+ 3.33 C 2.00 D- 0.67
B 3.00 C- 1.67 F 0.00
If your son receives a "P", this is a "PASS" grade and does not factor into the
calculation of the grade point average, nor does the class factor into the number of
classes that is used to determine grade point average.
To calculate grade point average do the following:
Add the grade points for all classes that meet daily.
Add half the grade points for all classes that meet every other day.
Divide by the number of classes. (Classes meeting every other day count
* Note that your semester grade point average is based on the vertical letter grades
above this number and is independently calculated from the quarter-by-quarter grade
point average number running across the bottom of the report card.
