How to Calculate Grade Point Average

  1. Multiply the Grade Value by the Credit Value to calculate Quality Points
  2. Add the Quality Points to find Total Quality Points Earned.
  3. Add the Credits to find the Total Credits Attempted.  Year-long classes are all one credit classes and half-year or semester classes are all 0.5 credits.  The only exception is physical education classes which are 0.25 credits.
  4. Divide the Total Quality Points Earned by the Total Credits Attempted to find GPA.

Example of a Grade Point Average Calculation:

Class Grade Grade Value Credit Value Quality Points
English B 3.000 1.0 3.000
Math A- 3.667 1.0 3.667
Science B+ 3.333 1.0 3.333
U.S. History C+ 2.333 0.5 1.167
P.E. A 4.000 0.25 1.000
Band A 4.000 1.0 4.000
Food for Fitness B- 2.667 0.5 1.333
Total Quality Points 17.167
Total Credits 5.25
GPA 3.270
Regular grading system at the high school:
A = 93-100 = 4.000 C = 73-76 = 2.000
A- = 90-92 = 3.670 C- = 70-72 = 1.670
B+ = 87-89 = 3.330 D+ = 67-69 = 1.330
B = 83-86 = 3.000 D = 63-66 = 1.000
B- = 80-82 = 2.670 D- = 60-62 = 0.670
C+ = 77-79 = 2.330 F = 59-Below = 0.000
Weighted grading scale and point values for AP courses:
A = 93-100 = 5.000 C = 73-76 = 3.000
A- = 90-92 = 4.670 C- = 70-72 = 2.670
B+ = 87-89 = 4.330 D+ = 67-69 = 2.330
B = 83-86 = 4.000 D = 63-66 = 2.000
B- = 80-82 = 3.670 D- = 60-62 = 1.670
C+ = 77-79 = 3.330 F = 59-Below >= 0.000
