Printable score lookup
Easy grader table
Set the assignment once, then scan every possible points-off result. This page serves the lookup and print job; the stack grader serves a continuous paper-by-paper session.

How the table is calculated
Each row subtracts points off from the total possible points. The remainder is divided by the total and multiplied by 100. If an assignment has 20 possible points and a paper loses 2 points, the score is 18 ÷ 20 × 100 = 90%.
When to use half or quarter points
Choose a smaller step only when your rubric awards partial credit. It creates more rows, but it does not change the formula. The displayed percentage follows the selected rounding rule; the unrounded value is not silently replaced in the underlying calculation.
Why this is a separate page
A printable chart is a different output from a live grading session. Keeping the chart here avoids creating many near-identical pages for “10-question,” “20-question,” or other totals. The total is an input, not an indexable URL.
