How do I calculate what I need on my final exam?

Enter your current grade percentage (before the final), your desired final grade, and how much the final exam is worth (as a percentage). The calculator will instantly show you the exact score you need on the final exam.

What if the required score is over 100%?

If the calculator shows a score over 100%, it means your desired grade is not achievable with your current grade and the final exam weight. You may need to consider extra credit opportunities or adjust your target grade.

How is the final exam score calculated?

The calculation uses this formula: Required Score = (Desired Grade - Current Grade × (1 - Final Weight)) / Final Weight. For example, if you have 85% and want 90%, with a 40% final weight, you need (90 - 85×0.6) / 0.4 = 97.5% on the final.

What do the multiple scenarios show?

The scenarios table shows what scores you need for different target grades (A, B, C, etc.), helping you see all your options at once. It marks each scenario as achievable or not possible based on the required score.

Can I save my calculations?

Yes, your inputs (current grade, desired grade, and final weight) are automatically saved in your browser, so they will be there when you return to the calculator.
