We typically reply within a few business days. When reporting a calculator issue, include the tool name and the exact numbers you entered (and the grading scale you expected) so we can reproduce it.
What we're looking for
- Calculators you wish existed (especially GPA, grading, and exam-planning tools)
- Results that look wrong, with your inputs
- A grading scale or GPA policy that differs at your school, with a reference
- Wording or formulas that could be clearer
For how our tools are computed and the scales behind them, see the about page, or browse the guides for the math step by step.
