Features
Computes the percentage with one-decimal precision and maps it to the standard A/B/C/D/F scale. Also shows how many you missed and what each question was worth.
Benefits & Use Cases
Students estimate grades right after a test, teachers sanity-check gradebook entries, and quiz-takers convert raw scores before official results arrive.
Tips
The A–F cutoffs used here are the common 90/80/70/60 bands — your school may curve differently, so treat the letter as an estimate.
Frequently Asked Questions
How is the percentage calculated?
Correct answers divided by total questions, multiplied by 100.
What grade bands are used?
A ≥90%, B ≥80%, C ≥70%, D ≥60%, F below 60% — the most common US scale.
Does it handle extra credit?
If your correct count exceeds the total through extra credit, scores over 100% are shown as-is.
Can teachers use it for whole classes?
It grades one test at a time — handy for spot checks, though a spreadsheet suits full classes better.
