Equal-value questions only. Grades use unrounded percentages; displayed scores use
up to two decimals. For partial credit or a custom scale,
use the test calculator.
EZ grader: questions 5 to 100
The EZ grader gives the score for every wrong-answer count shown at that length. This reference contains every whole-number test length from 5 to 100 and columns for 0 to 20 wrong answers. A 25-question test with 4 wrong is 84%, a B on the standard scale.
The reference always uses 90/80/70/60 thresholds. The separate calculator below handles partial credit, other totals, and custom thresholds without changing the fixed reference above.

WHO IT HELPS & HOW TO USE IT
How to use easy grader
For teachers who need a score lookup or a printable chart for a particular test.
In the reference matrix, find the total questions row and move across to the number wrong.
For a 50-question print chart, set Total questions to 50 in the focused calculator below the matrix and choose your scale and step size.
Choose Print (Print score chart) or export its CSV. The focused chart includes the full score range, even when the on-screen chart is paginated.
Before you rely on the result: The fixed matrix covers 5–100 equal-value questions and 0–20 wrong, using standard 90/80/70/60 thresholds. Custom settings affect only the separate focused chart.
Find the row matching your total number of questions, then move across to the column matching wrong answers. The cell gives the percentage and letter grade. For 20 questions and 3 wrong, read 85%, B.
This reference covers every whole-number test length from 5 through 100 and columns from 0 through 20 wrong. A dash means the wrong-answer count exceeds the number of questions. Scroll horizontally to see all columns.
The matrix uses equal-value questions and the standard A–F scale. The calculator below creates a focused chart for other totals, fractional points, more than 20 wrong answers, or custom grading thresholds.
GOOD QUESTIONS. STRAIGHT ANSWERS.
Easy Grader: frequently asked questions
How do I read this easy grader table?
Rows are total questions and columns are wrong answers. Locate their intersection to read the percentage and letter. Use Find your test to jump to a row.
Which letter-grade scale does the reference chart use?
The matrix uses A ≥90%, B ≥80%, C ≥70%, D ≥60%, and F below 60%. Changing the calculator’s scale does not change this reference matrix.
What if my test has fewer than 5 or more than 100 questions?
Use the focused calculator below the reference. It supports positive totals up to 10,000 points and generates a chart for your test.
Where do I look for more than 20 wrong answers or fractional marks?
Use the focused calculator below. Its chart covers every score at the selected step size; large charts are paginated, while print and CSV include all scores.
