Calculate an exam percentage from points earned and points possible, then see how the exam contributes to a weighted class grade. This is useful after receiving a test score or when checking how a practice score would affect a course category.
The main result is the exam percentage. The weighted contribution shows how many percentage points the exam adds to the final course grade when the exam weight is known. It does not calculate the entire course grade unless all other course components are included separately.
1. Enter points earned
Use the credited score after any instructor adjustments.
2. Enter points possible
Use the total available points on the exam.
3. Enter the course weight
Use the percentage of the final course grade assigned to this exam.
4. Review both results
Distinguish the exam percentage from its weighted contribution.
Exam score = Points earned ÷ Points possible × 100
Weighted course contribution = Exam score × Exam weight. Convert the weight to a decimal before multiplying.
The exam score is the percentage of available points earned.
Curves, extra credit, question weighting, and category rules can change the official grade.
Given: 82 points earned out of 100, with the exam worth 25% of the course.
Calculation: 82 ÷ 100 × 100 = 82%; 82% × 0.25 = 20.5 percentage points.
Result: The exam score is 82%, contributing 20.5 points to the final course grade.
This version assumes earned points do not exceed possible points. Add extra credit according to your instructor’s method.
No. It is only the exam’s contribution to the final grade.
Use the final weighted point totals reported for earned and possible points.
Only if you enter the curved earned score and corresponding points possible.
The exam percentage measures performance on the test; contribution also applies the exam’s course weight.
