Use W to add a wrong answer and R to reset while grading papers, or click the controls. The chart updates for every possible score and can be copied for reuse.
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.
Set the number of questions, then grade papers quickly with the wrong-answer stepper or the W keyboard shortcut. R resets to zero wrong. Half-point mode and an editable scale change the generated chart.
The chart assumes equal-value questions. If individual questions have different point values, calculate using earned/possible points instead of question counts.
Question count, points per question, half-points, rounding, and the letter scale can all change the cutoff table. Save or copy the chosen scale with the chart so a later score is not interpreted using different settings.
A displayed 90% can represent a range of underlying values when the course rounds to whole percentages. If a boundary matters, compare the unrounded points earned with the syllabus rule rather than relying only on the formatted percentage.
This page is strongest for one test or equal-point question sets. Category weighting, dropped scores, extra credit, late penalties, and course-level GPA rules should be handled with the corresponding grade or GPA calculator instead of being inferred from this chart.
