How this result is calculated
required final = (target − current × (1 − final weight)) ÷ final weight
(85 − 88 × (1 − 0.3)) ÷ 0.3 = 78.0%.
What-if comparison
Final score scenarios
What grade do I need on my final?
Enter your current grade, target course grade, and final exam weight. The calculator treats your current grade as covering the non-final portion of the course, then solves backward for the final score.
If your course uses several weighted categories or the final sits inside a category, calculate the current course position first with the Weighted Grade Calculator.
Possible, impossible, and already secured targets
A required score above 100% means the target cannot be reached without extra credit under the entered assumptions. GradeCompute reports the maximum possible course grade instead of treating that result as an error. A required score at or below 0% means the target is already secured.
Percentage, points, and multi-part finals
Percentage mode uses current grade and final weight. Points mode solves for the final points needed from accumulated and remaining points. Multi-part mode first combines visible parts of the final, then applies the final's course-level weight.
Scenario cards show what several possible final scores would do without changing the main result. The share link uses a URL fragment and contains numeric assumptions only.
Final grade FAQs
What grade do I need on my final?
Enter the current grade, target, and final weight. The required score is solved immediately.
What does a required score above 100% mean?
The target is mathematically impossible without extra credit under the entered model.
How do I calculate my course grade after the final?
Choose Final completed and enter the final score with its course weight.
Can a final have several parts?
Yes. Multi-part mode combines two visible parts before applying the final's course weight.
Can I use points instead of percentages?
Yes. Points mode solves from points earned, current possible points, final possible points, and the target percentage.
What if the final is a weighted category?
Use the Weighted Grade Calculator to model the category, then return here only if the final has its own course-level weight.
