Purpose and steps
Exam Weighted Grade Calculator validates rows: grade (%), weight (%) before applying the displayed equation. The total supplied weight must be above 0 and at most 100%.
- Combine exam results using their stated weights. Weights below 100% produce an average of the supplied portion; the uncovered remainder is reported separately.
- Enter Rows: grade (%), weight (%) in the stated format. Baseline values are for reproduction.
- Check the output unit and convention: Read weighted grade (normalized over supplied weights) with its stated unit and convention. The default example and the independent worked scenario use different inputs, so compare the assumptions before comparing the numbers.
- Change one input and compare the result. The total supplied weight must be above 0 and at most 100%. An unfilled assessment is not silently treated as a zero grade.
Input reference and units
These values reproduce the model’s demonstration. Replace them with your own records or measurements; they are not recommended targets.
On a small screen, swipe the table horizontally to see all columns.
| Parameter | Demonstration value | How to enter it |
|---|---|---|
| Rows: grade (%), weight (%) | 80 40 90 60 | One item per line; match the columns in “Rows: grade (%), weight (%)”. Do not include a header row. |
Model-specific method
How this calculator produces its result
Exam Weighted Grade Calculator: grade = Σ(score × weight) / Σweight. Input definitions: rows = Rows: grade (%), weight (%). Use the selected convention throughout the calculation.
Exam Weighted Grade Calculator: calculation relationships
Combine exam results using their stated weights. Weights below 100% produce an average of the supplied portion; the uncovered remainder is reported separately. The total supplied weight must be above 0 and at most 100%. An unfilled assessment is not silently treated as a zero grade.
Normalize only over supplied assessment weights. Scores 80 and 100 with weights 25 and 75 give (80×25 + 100×75)/100 = 95%. If supplied weights total 50, the denominator is 50: the answer describes the completed portion, not the final course grade. The covered-weight output keeps that distinction visible.
grade = Σ(score × weight) / Σweight
- rows: Rows: grade (%), weight (%). One item per line; match the columns in “Rows: grade (%), weight (%)”. Do not include a header row.
- Result units: stated beside each output
- Calculation relationship: grade = Σ(score × weight) / Σweight
- Supported domain: see the limits below
Worked example
Exam Weighted Grade Calculator baseline input: Rows: grade (%), weight (%): 80 40 / 90 60. Output: Weighted grade (normalized over supplied weights) = 86; Covered course weight = 100 %. Substitute these values into the displayed equation to reproduce the result.
Reproduce the default scenario
This reproduces the default inputs in the reference table above; it is not an additional independent example. Displayed rounding may differ from intermediate precision.
- Weighted grade (normalized over supplied weights)
- 86
- Covered course weight
- 100%
Reading results without overstating them
- Read weighted grade (normalized over supplied weights) with its stated unit and convention. The default example and the independent worked scenario use different inputs, so compare the assumptions before comparing the numbers.
- Change one input at a time and use the equation to explain the result; do not mix unit, grade-scale, time-zone or rounding conventions across comparisons.
Assumptions and exclusions
- The total supplied weight must be above 0 and at most 100%.
- An unfilled assessment is not silently treated as a zero grade.
