How to Use This Grade Calculator

If you know your current grade, the grade you want, and how much the final exam is worth, you can work out the score you need on that final. The part of your grade already decided is your current grade times the weight that is not the exam; the rest must come from the exam itself, so the needed score is the gap divided by the exam weight. If the answer is above 100%, even a perfect final cannot reach the target — then the target needs to change.

Formula Used

Score needed on the final = (target − current × (1 − exam weight)) ÷ exam weight. If the answer is above 100%, the target cannot be reached even with a perfect final.

Worked Example

Example: Current grade 82% · Target grade 85% · Final exam weight 30%

  1. The part of your grade already decided is 82% × (1 − 0.30) = 82% × 0.70 = 57.4%.
  2. The final must supply 85% − 57.4% = 27.6% of the total grade.
  3. Needed on the final = 27.6% ÷ 0.30 = 92.00% — achievable, but it needs a strong exam.

You Need on the Final: 92.00%

Frequently Asked Questions

The answer is over 100% — what does that mean?

Even a perfect score on the final cannot reach your target. You would need to lower the target, ask whether extra credit is possible, or accept the highest grade you can reach.

What does the exam weight mean?

How much of your final grade the exam decides. A 30% weight means the exam is worth 30 points out of 100 in the final grade, and everything else is worth 70.

Does the calculator allow for curved grades?

No. It assumes straight weighting with no curve. If your teacher curves grades, the result is a rough guide, not a promise.
