How to Calculate Your G.P.A.
Your G.P.A. is your grade-point average. A G.P.A. is determined by letter grades.
Although different schools may use slightly different formulas for calculating a student’s G.P.A., all formulas are based on the sort of scale to the left [see worksheet]. Imagine that these are your grades for the quarter: Algebra I-A; World History-B; English I-B; Physical Education-C; General Art-B+; Earth Science-A.
What is the G.P.A. for these grades? All you need to do is find the grade-point value for each course and average these grade-point values.
Algebra I-A 4.0; World History-B 3.0; English I-B- 2.7; Physical Education-C 2.0; General Art-B+ 3.3; Earth Science-A- 3.7; then tally them up and find the average: 4.0 + 3.0 + 2.7 + 2.0 + 3.3 + 3.7 = 18.7 ÷ 6 = 3.12. The G.P.A. for this set of grades is 3.12, which equates to a “B” average for the quarter.
1. Many schools give "weighted grades" to honors courses. When this is done, the grade-point value for an honors course is increased by one. For example, a "B" in Honors English is worth 4.0 rather than 3.0. This is how some honors students are able to have a G.P.A. higher than 4.0.
2. The standard cut-off for "honor roll" is a G.P.A. of 3.5.
3. Universities award "Latin honors" of cum laude for a G.P.A. of at least 3.5, magna cum laude for a G.P.A of at least 3.7, and summa cum laude for a G.P.A. of at least 3.9. (Check with a particular university for its specific cut-offs.)
