A test grade calculator is an essential academic tool that converts raw test scores into percentages and letter grades. Whether you're a student wanting to quickly check your grade or a teacher grading dozens of papers, this calculator provides instant, accurate results using the standard grading formula.
Or equivalently: Percentage = (Correct ÷ Total) × 100
This is useful when you only know the number of incorrect answers.
Select whether you want to enter number wrong, number correct, or points earned.
Input the total number of questions or maximum possible points on the test.
Input the number wrong, number correct, or points earned depending on your chosen mode.
Choose from Standard (A-F), Plus/Minus, 7-Point, 10-Point, or Pass/Fail scales.

A student takes a 40-question test and answers 7 questions incorrectly. What is their grade?
Percentage = 0.825 × 100 = 82.5%
Letter Grade: B
Result: With 33 correct out of 40 questions, the student earns 82.5%, which is a B grade on the standard scale (or B- on the plus/minus scale).
A student earns 85 points out of 100 possible points on a midterm exam. Calculate their grade.
Percentage = 0.85 × 100 = 85%
Letter Grade: B
Result: The student earns 85%, which is a solid B grade.
A student answers 2 questions wrong on a 25-question pop quiz. What percentage and letter grade do they receive?
Percentage = 0.92 × 100 = 92%
Letter Grade: A- / A
Result: With only 2 wrong, the student scores 92% - an A- on the plus/minus scale or A on the standard scale!
A student gets 12 out of 20 questions correct on a final exam. Did they pass (60% required)?
Percentage = 0.60 × 100 = 60%
Letter Grade: D
Result: The student scores exactly 60%, which is a D grade - just barely passing! One more wrong answer would have resulted in failing.
| Grade | Standard (10-Point) | Plus/Minus | 7-Point (Strict) | GPA Points |
|---|---|---|---|---|
| A+ | - | 97-100% | - | 4.0 |
| A | 90-100% | 93-96% | 93-100% | 4.0 |
| A- | - | 90-92% | - | 3.7 |
| B+ | - | 87-89% | - | 3.3 |
| B | 80-89% | 83-86% | 85-92% | 3.0 |
| B- | - | 80-82% | - | 2.7 |
| C+ | - | 77-79% | - | 2.3 |
| C | 70-79% | 73-76% | 77-84% | 2.0 |
| C- | - | 70-72% | - | 1.7 |
| D | 60-69% | 60-69% | 70-76% | 1.0 |
| F | 0-59% | 0-59% | 0-69% | 0.0 |
The most common grading scale in U.S. education. Each 10-percentage-point range corresponds to one letter grade.
A more rigorous scale often used in competitive academic environments. An A requires 93% or higher.
Each question = 10%
Each question = 5%
Each question = 4%
Each question = 2%
Double-check whether you're entering the number of wrong answers or correct answers. Getting 7 wrong on a 40-question test (82.5%) is very different from getting 7 correct (17.5%).
Some tests award partial credit. If your test has partial credit, use the "Points" mode instead of counting questions as fully correct or wrong.
Always check your syllabus or ask your teacher which grading scale they use. An 89% might be an A- on some scales but a B+ on others.
If your test includes extra credit questions, your total points possible should include only the regular questions unless the extra credit is mandatory.
Before the test, calculate how many questions you can miss and still get your desired grade. For a 20-question test, missing 2 still gets you 90% (A).
After getting your test back, analyze your mistakes. Understanding why you got answers wrong helps prevent similar errors in the future.
Divide your test time by the number of questions. If you have 60 minutes for 40 questions, spend about 1.5 minutes per question.
Unless there's a penalty for guessing, never leave questions blank. A guess gives you a chance; a blank answer is automatically wrong.
In most U.S. schools, 60% is the minimum passing grade, corresponding to a D. However, some schools or courses may require 65% or 70% to pass. College courses often require a C (70-73%) minimum. Always check your course syllabus for specific requirements.
Use the "Points" mode instead of "# Wrong" or "# Correct." Enter your total points earned and total points possible. For example, if you earned 78 out of 100 possible points (with some questions worth more than others), enter 78 as points earned and 100 as points possible.
It depends on your teacher's rounding policy. Some teachers round 89.5% up to 90% (A), while others keep it at 89% (B+). On the standard scale without plus/minus grades, 89.5% would round to 90% and be an A. Check with your teacher about their specific rounding policy.
For an A (90%+) on a standard scale: On a 10-question test, miss 1; on a 20-question test, miss 2; on a 25-question test, miss 2; on a 50-question test, miss 5; on a 100-question test, miss 10. Use our calculator to find exact thresholds for any test size.
This test grade calculator calculates unweighted grades - each question has equal value. Weighted grades give different values to different assignment types (e.g., tests worth 40%, homework worth 20%). For weighted grade calculations, use our Grade Calculator.
Yes! Switch to "Points" mode and enter your points earned and total points possible. For example, if a test has 20 multiple choice (1 point each = 20 points) and 4 essays (5 points each = 20 points), the total is 40 points. Enter your total points earned out of 40.
Extra credit can push your score above 100%. Use "Points" mode: enter your total points (including extra credit) as "Points Earned" and the original maximum as "Points Possible." For example, 105 points earned out of 100 possible = 105%.
A "good" grade is subjective and depends on context. Generally: 90%+ (A) is excellent, 80-89% (B) is above average, 70-79% (C) is average/satisfactory. For college applications, aim for A's and high B's. For graduate school, mostly A's are expected.

Our Test Grade Calculator makes it easy to convert your test scores into percentages and letter grades. Whether you just finished a quiz and want to know your grade before the teacher posts it, or you're a teacher grading papers, this tool provides instant, accurate results with multiple grading scale options.
Remember: a single test grade is just one measure of your learning. Use this calculator to track your progress, but focus on understanding the material rather than just the numbers. Consistent effort and learning from mistakes will lead to better grades over time.
