Reporting a calculator issue
Please include:
- The page or calculator you used.
- The input values and any scale or rounding settings.
- The result shown and the result you expected.
- Your browser and device if the issue involves the layout or controls.
For example: “Easy grader: 20 questions, 3 wrong, default scale. I expected 85%.” An anonymous example is enough; do not include student names, IDs, report cards, passwords, or private school records.
Before you send a message
The methodology page explains the formulas. The grading-scale guide explains why letter grades can differ between courses. Questions about official grades or course-specific policies should go to the relevant teacher or institution.
