Grade Calculator
The exam score you need to reach your target final grade.
Quick answer
- Formula: Required score = (Desired final − Current × (1 − exam weight)) ÷ exam weight
- Worked example — Required exam score: 80.00% (full example below).
Grade Calculator
| Required exam score | 80.00% |
| Assessment | Achievable: this is the minimum exam score needed to reach your target. |
Holding 90% with a final worth 20%, you need 80% on the exam to finish at 88%.
Enter the grade you have so far, how much the final exam is worth, and the final grade you want. This calculator solves for the exact exam score required.
If the answer is above 100%, the target cannot be reached with the exam alone — the calculator says so honestly instead of capping the number, so you can adjust your target or look for extra credit.

Frequently asked questions
What if the required score is over 100%?
The target is mathematically out of reach through the exam alone. Options include extra credit, dropping a low score if your syllabus allows it, or aiming for the highest reachable grade below your original target.
What if the required score is negative?
Your target is already secured — even a 0% on the exam would leave your final grade at or above the desired level.
