Most grade calculators do one lookup at a time. This one's built for grading a whole stack fast: tap "+1 wrong" (or press W) per miss instead of retyping numbers, hit Reset for the next student. Decimal precision keeps partial credit accurate. The grading scale is fully customizable to match your school's policy. No sign-up, no data collection, everything runs in your browser. Includes a separate percentage-to-letter converter and a grading guide too.
