Enter total questions and wrong answers for an instant score, switch to correct-answer mode when useful, customize the grading scale, and copy the complete wrong/correct/percent/letter chart.
Cross-check correct, wrong, percentage and the active letter-grade threshold before copying a result.
Use the dedicated calculator that matches the decision you are making instead of forcing one formula onto every grading problem.
| Scenario | Input | Outcome | Interpretation |

Calculate test percent and letter grade, then verify correct/wrong counts, points, pass threshold and rounding-sensitive score targets.
Independently rebuild the current grade/GPA scenario from the visible inputs, check denominator or weight completeness, and show feasible outcome boundaries. This is a planning cross-check, not a replacement for the school’s official gradebook policy.
Separate question-count tests, pure points, weighted categories, final-exam weighting and GPA scales. Then reconcile the calculator with the syllabus rule actually used by the class.
Enter total questions and either wrong or correct answers. The calculator shows percentage, points, letter band, and the complete grading chart; half-point mode changes the chart step to 0.5.
Letter cutoffs are editable because schools and instructors use different scales. “Points per question” assumes equal-value questions; use a points-based calculator when questions have different values.
