FAQs
What grading scale does it use?
It uses the widely recognised scale of 90% for an A, 80% for a B, 70% for a C, 60% for a D and below 60% for an F. Grading scales vary between schools, so always check your institution’s own boundaries.
What if my score is higher than the total?
That usually means extra credit was awarded. The calculator still works out the percentage and shows a note explaining the situation.
Can I enter decimal marks?
Yes. Both fields accept decimals, so marks like 37.5 out of 40 are no problem.
Is any of my data stored?
No. All calculations happen locally in your browser, and the marks you enter never leave your device.
