Formula Used
The weighted grade formula used in most college grading systems is:
Final Grade =
(S1 × W1 + S2 × W2 + S3 × W3) ÷ Sum of the weights
Where:
- S = score obtained
- W = weight percentage
For GPA calculations:
GPA = Total Grade Points ÷ Total Course Credits
This formula determines the average GPA value across multiple courses.
Example Calculation
Example:
Assignment score = 85
Exam score = 78
Final exam score = 90
Weights:
Assignments = 30%
Exams = 30%
Final exam = 40%
Calculation:
(85 × 0.30) + (78 × 0.30) + (90 × 0.40)
Result:
Final grade = 84.6%
According to most college grading scales, this corresponds to a B letter grade.
