A grade chart, also called a grading chart or easy-grader table, matches raw scores with percentages and letter grades. Each row shows how the result changes when one more answer is correct or wrong.
10-question grade chart
This example uses whole-point scoring and a simple A–F scale. Use the generator above to create the same chart for any test from 1 to 500 questions with standard, strict, or lenient letter-grade thresholds.
| Wrong | Correct | Percentage | Letter grade |
|---|---|---|---|
| 0 | 10 | 100% | A |
| 1 | 9 | 90% | A |
| 2 | 8 | 80% | B |
| 3 | 7 | 70% | C |
| 4 | 6 | 60% | D |
| 5 | 5 | 50% | F |
| 6 | 4 | 40% | F |
| 7 | 3 | 30% | F |
| 8 | 2 | 20% | F |
| 9 | 1 | 10% | F |
| 10 | 0 | 0% | F |
How to read a grade chart
Find the number of points or questions missed in the first column. Move across the row to see the number correct, percentage score, and corresponding letter grade. A zero in the wrong column represents a perfect score.
Printable grading chart for teachers
Generate the chart for the test you are marking, then print it. The chart prints on its own as a clean table with no site furniture, so it can be laminated and kept beside the answer key as a reusable marking key. Because the letter-grade column follows the scale preset you pick, set standard, strict, or lenient before printing so the printed chart matches your course policy.
Grading chart vs. the E-Z Grader
The paper E-Z Grader is a sliding cardboard chart teachers have used since the 1950s: set the number of problems, find the number wrong, and read the percentage. A digital grading chart is the same lookup table without the card — it covers any test length from 1 to 500 questions and never needs re-aligning. The history of the Easy Grader covers where the tool came from.
Create a chart for any assignment
Test length, fractional scoring, bonus points, and grade thresholds can all change the chart. Generate a custom chart instead of relying on a fixed printable table.
How many questions can a student miss?
Find the required percentage in the chart and read the wrong-answer value in the same row. On a 20-question test, each question is worth 5 percentage points, so 6 wrong answers produce 70%. Shorter quizzes have larger gaps between possible scores because each question represents more of the total.
Grading scale for a specific number of questions
Every test length has its own fixed grading scale because each question is worth 100 ÷ total questions. These pages show the full wrong-answer-to-letter-grade table for the most common test sizes:
- Grading scale for 10 questions
- Grading scale for 12 questions
- Grading scale for 15 questions
- Grading scale for 20 questions
- Grading scale for 25 questions
- Grading scale for 30 questions
- Grading scale for 40 questions
- Grading scale for 50 questions
- Grading scale for 60 questions
- Grading scale for 100 questions
Grade charts for partial credit
A whole-question chart assumes every item has equal value. For half points, quarter points, essay rubrics, or different question weights, use the full grade calculator and select the required point precision. The chart will include fractional raw scores.
