Test Score Calculator
Know exactly how you performed on any test.
How to Use This Tool
- Enter points earned.
- Enter total possible points.
- Get percentage and letter grade.
The Formula
Percentage = (Earned / Total) × 100. Standard grading scale: A 93-100%, B 83-92%, etc.
Why It Matters
You scored 42/50 on a chemistry midterm. That is an 84% — a B grade. You need 47/50 on your next test (94%) to raise your class average to an A. Alternatively, you only need 22/25 on the final to secure a B+ in the course, helping you maintain scholarship eligibility.
