How this tool works
Score percentage equals correct answers or earned points ÷ total questions or possible points × 100.
Limits to know
The percentage divides entered earned points by possible points. Curves, partial credit, penalties, dropped items, extra credit, rounding, and letter-grade policy require the teacher's rules.
