Calculate a weighted course grade and estimate the average score required on remaining work to reach a target final grade.
Weighted grades
Each assignment score is multiplied by its weight. The weighted contributions are added to calculate the current grade across completed work.
Check the weights
Completed assignment weights should not exceed 100%. Remaining weight is the portion of the course still available to affect the final grade.
Final grade planning
If you have a target grade, the calculator estimates the average score required on the remaining work. A required score above 100% means the target is no longer mathematically reachable under the stated weights.
Different grading policies
Some schools drop the lowest score, curve grades or use category weighting. Those rules must be applied before using a simple weighted-average model.
How to use it
Enter each known score and its weight, then set the target. Compare the required remaining score with realistic performance expectations.
Practical use
This is useful for students planning exams, assignments and final grades when the course weighting is known.
Worked example: weighted final grade
If homework is worth 30% and the average is 90%, its contribution is 27 percentage points. If exams are worth 70% and the exam average is 80%, their contribution is 56 points. The weighted final is therefore 83%.
Planning a target grade
For remaining work, use the weight that is still available rather than treating the remaining percentage as another ordinary score. A required result above 100% indicates that the target cannot be achieved under the current assumptions.
Check the course policy first
Grade replacement, dropped assignments, extra credit and category weighting can materially change the calculation. Use the published grading policy before entering values.
Weighted Grade Formula
Final Grade = Sum of Weighted Contributions
Use weights as percentages or their decimal equivalents consistently. For example, a score of 90% with a 30% weight contributes 27 percentage points.
Planning a Target Grade
If some course weight remains, the required average on that remaining work can be calculated from the target, current weighted contribution and remaining weight. A required score above 100% means the target is not mathematically reachable under the stated assumptions.
Worked Example
If completed work contributes 54 points and 30% of the course remains, a target of 80% requires 26 additional points. The required average on the remaining 30% is therefore 86.67%.
Check the Course Policy
Grade replacement, dropped assignments, category weighting, extra credit and curves can change the calculation. Entering individual scores into a simple weighted model does not automatically reproduce those policies.
Incomplete Weight vs Completed Weight
Do not treat the remaining percentage as another ordinary score. The remaining weight represents how much influence future work still has on the final result.
