Test Grade Calculator
Enter either correct or wrong answers plus total questions to turn a test or quiz score into a percentage, missed-question count and letter-grade reference.
How to calculate a test grade
Divide the number of correct answers by the total number of questions, then multiply by 100. If you only know how many answers were wrong, select Wrong answers; Lynara subtracts that count from the total before applying the same formula.
test grade % = correct answers ÷ total questions × 100
Test and quiz examples
- 23 correct out of 25: 92%, with 2 questions missed.
- 2 wrong out of 25: the same 92% result.
- 17 correct out of 20: 85%, with 3 questions missed.
- Extra credit or curves: use the grading rule supplied by your instructor rather than silently adding points here.

Questions
Can I enter wrong answers instead of correct answers?
Yes. Switch the score-entry mode to Wrong answers; Lynara converts the count back to correct answers before calculating the percentage.
Can correct or wrong answers exceed the total?
No. The calculator rejects impossible counts.
How is the letter grade chosen?
A common US reference scale is shown, but your course may differ.
