How to calculate weighted average grade?
Below are the steps to calculate weighted average grade:
1. Determine Grade and Weight: Determine your grade on each assignment and the weight of the grade.
2. Multiply Grade by Weight: Multiply the grade on the assignment by the grade weight.
3. Add together.
Weighted grade = w1×g1+ w2×g2+ w3×g3+...
Example:
Language course with grade of 85 and weight of 35%.
Science course with grade of 80 and weight of 40%.
History course with grade of 75 and weight of 25%.
The weighted average grade is calculated as:
 = 35%×85 + 40%×80 + 25%×75 = 80.5
When the weights of modules are not in percentage, an additional step is required: divide the weighted sum by the sum of the weights:
Example:
Language grade is 80, earned 3 credits.
Science grade is 90, earned 5 credits
History grade is 75, earned 2 credits
Weighted average grade is calculated as:
