How the Calculator Works
The calculator performs a weighted grade calculation by multiplying each score by its assigned weight.
After multiplying the values, the calculator adds the results and divides by the sum of the weights to determine the final course grade.
This method ensures accurate grade evaluation because the calculator uses the same formula applied in many grading systems used by schools and universities.
Formula Used
The standard formula for calculating a weighted course grade is:
Course Grade =
(S1 × W1 + S2 × W2 + S3 × W3) ÷ Sum of weights
Where:
S = score obtained
W = weight percentage
This formula determines the weighted average grade for the course.
Example Calculation
Example:
Homework score = 85
Quiz score = 90
Exam score = 80
Weights:
Homework = 30%
Quiz = 20%
Exam = 50%
Calculation:
(85 × 0.30) + (90 × 0.20) + (80 × 0.50)
Result:
Final course grade = 83.5%
