FINAL EXAM GRADE NEEDED

How the final grade math works

Your final grade blends what you have already earned with your final exam. The calculator runs that blend in reverse:

Your current grade counts for everything except the final (100 minus the final weight).
Subtract that contribution from the grade you want.
Divide by the final exam weight. That is the score you need.

The formula: needed = (desired − current × (1 − weight)) ÷ weight

Example: 85% now, aiming for 90%, final worth 30%. You would need (90 − 85 × 0.70) ÷ 0.30 = 101.67%. Over 100% means the goal is out of reach, so you can reset your target early.

Frequently asked questions

Enter your current grade, your passing mark (for example 60%) as the desired grade, and the final exam weight. The calculator shows the exact score you need.

Then the desired grade is mathematically impossible at the current weight, even with a perfect final. Lower your target or ask about extra credit.

Yes. Switch the grade scale to Letters and choose your current and desired grades from A+ to F. Each letter converts to a standard numeric value, and the answer shows as a letter too.

You have already secured your desired grade. Even a zero on the final keeps you at or above your target.
