  • Needed = (target − current × (1 − weight)) ÷ weight. Rounded up, since a score a fraction below it falls short.

What it does

Final Exam Grade Calculator works out the score you need in the final exam to finish a course with the overall grade you want. It needs three numbers: your grade so far, before the final, as a percentage; how much the final is worth in the overall grade, from the syllabus; and the overall grade you are aiming for. Your current grade counts for the rest of the weight, so with 72% so far and a final worth 40%, the coursework contributes 72 × 0.6 = 43.2 points and the final must bring the other 36.8 — a score of 92%. The answer is rounded up, because a score a fraction below it would fall just short. If the target is already secured even with 0 in the final, it says so; if it would take more than 100%, it says that it cannot be reached with the final alone. A table under the result shows the score needed for the common boundaries from 90% down to 40%, so you can see what each grade would take.

How to use it
  1. Enter your current grade before the final, as a percentage.
  2. Enter the final exam’s weight in the overall grade.
  3. Enter the overall grade you want.
  4. Read the score needed and the table of other targets.
Limits and your data
  • It assumes the overall grade is a straight weighted average of the coursework and the final. Courses with a minimum mark in the final, dropped lowest scores or curves need their own rules applied.
  • If your current grade is not yet a percentage of the coursework done, work that out first: your marks so far over the marks available so far.
  • Everything is calculated in your browser. Nothing you type is sent anywhere.

Questions

What score do I need on my final to get an A?

Enter the percentage your course needs for an A (often 90 or 80) as the target. The table shows the common boundaries at once.

Why is the answer rounded up?

Because the target is a minimum. Rounding down could give a score that leaves you a hundredth short.

What if the final is worth 100%?

Then your current grade does not count and the score needed is the target itself.

Can I use it for a midterm or any weighted exam?

Yes. Enter that exam’s weight and your grade on everything else so far.
