Hi Product Hunt 👋 I built Grade Calculator because every existing "grade calculator" / "easy grader" tool is either buried in ads or missing the case I actually needed. The core tool does the simple job — wrong answers → percentage + letter grade + a printable chart. On top of that there's a points / point-system calculator, a weighted gradebook calculator, a grading-scale converter, ready-made tables for common test sizes (10–100 questions), GPA calculators, and a final-grade calculator. Everything is free, no sign-up, and nothing is stored on a server — the math runs in your browser. Feedback very welcome, especially from teachers.
