📘 About the Final Grade Needed
Enter your current grade in the course, the overall grade you want, and how much the final exam counts. The calculator tells you the minimum you must score on the final.
If the score needed is above 100%, the target is out of reach (unless there is extra credit); if it is below 0%, you have already secured it.
🧮 Formula
Your current grade must cover all the work before the final.
✏️ Worked examples
80% now, want 85%, final worth 30%
You get| Score needed on the final | 96.67% |
| Overall grade if you score 100% | 86% |
| Overall grade if you score 0% | 56% |
(85 − 80 × 0.7) ÷ 0.3 = 96.67%.
Try this example →92% now, want 90%, final worth 40%
You get| Score needed on the final | 87% |
| Overall grade if you score 100% | 95.2% |
| Overall grade if you score 0% | 55.2% |
87% is enough.

❓ Frequently asked questions
How do I calculate what I need on my final?
Subtract your current grade times (1 − final weight) from your target, then divide by the final weight. With 80% now, a target of 85% and a 30% final: (85 − 56) ÷ 0.3 = 96.7%.
What if the result is over 100%?
You cannot reach that target with the final alone. Check whether there is extra credit or aim for the next grade down.
