How to Calculate the Grade You Need on Your Final
Enter your current grade (before the final), the weight of the remaining assignment or final exam as a percentage of your overall grade, and the overall grade you're aiming for. The calculator works backward to tell you exactly what score you need on the remaining work to hit that target.
Example
You currently have an 82% average, and the final exam is worth 30% of your overall grade. To reach a 90% overall, you need: (90 − 82 × 0.7) / 0.3 = (90 − 57.4) / 0.3 = 108.7%. That's above 100%, meaning a 90% overall isn't achievable in this scenario — you'd need extra credit or a lower target.
Common Use Cases
- Figuring out what score you need on a final exam to reach a target course grade.
- Deciding how much a remaining assignment matters to your overall outcome.
- Checking whether a desired grade is still mathematically possible before the final.
FAQs
What does it mean if the required score is over 100%?
It means your desired overall grade isn't achievable with a normal final exam score — you'd need extra credit, or you should adjust your target to something realistically reachable.
What if the required score is negative?
A negative required score means you've already secured your target grade even with a zero on the remaining work — your current grade alone is high enough given the final's weight.
How do I find the weight of my final exam?
Check your course syllabus — instructors typically state each component's weight (like "Final Exam: 30% of grade") up front. If several items remain, add up their combined weight and treat that as one combined "remaining work" percentage.
