Enter your values and press Calculate.
Enter how many questions you answered correctly and the total number of questions on the test. The calculator divides your correct answers by the total questions and multiplies the result by 100 to give your test score as a percentage, rounded to two decimal places. Use the same steps for a quiz, an exam, an assignment, or a practice test. Then compare your percentage with the standard letter grade scale on the page to see the matching letter grade and GPA equivalent.
The test grade formula is the same on every competitor page because the maths is fixed: percentage equals correct answers divided by total questions, multiplied by 100. In symbols, percentage = correct / total × 100. If you answered 85 questions correctly out of 100, the calculation is 85 divided by 100, which is 0.85, and 0.85 multiplied by 100 is 85 percent. The score percentage formula works for any test size, from a 5 question pop quiz to a 200 question final exam, because it always measures the share of the test you got right. This page shows the formula next to the result, so you can check the working instead of trusting a hidden calculation.
Step one: count the questions you answered correctly and type that number into the Correct answers box. Step two: type the total number of questions on the test into the Total questions box. Step three: read your test score percentage in the result panel. That is the whole process, with no sign up, no download, and no extra fields. If you only know how many questions you got wrong, subtract that number from the total first: correct answers equals total questions minus wrong answers. For example, 3 wrong out of 20 questions means 17 correct, and 17 divided by 20 times 100 is 85 percent. Teachers grading a stack of papers can repeat the same two inputs for each paper in seconds.
A percentage on its own does not tell you the letter grade, so this page includes the standard letter grade scale used by most schools and colleges in the United States. On the simple scale, 90 to 100 percent is an A, 80 to 89 percent is a B, 70 to 79 percent is a C, 60 to 69 percent is a D, and below 60 percent is an F. On the fuller plus and minus scale, the bands are A+ 97 to 100, A 93 to 96, A minus 90 to 92, B+ 87 to 89, B 83 to 86, B minus 80 to 82, C+ 77 to 79, C 73 to 76, C minus 70 to 72, D+ 67 to 69, D 63 to 66, D minus 60 to 62, and F below 60. The GPA equivalent on the 4.0 scale runs alongside: A is 4.0, B is 3.0, C is 2.0, D is 1.0, and F is 0.0, with plus and minus grades worth 3.7 for A minus, 3.3 for B+, 2.7 for B minus, 2.3 for C+, 1.7 for C minus, 1.3 for D+, and 0.7 for D minus. Always check your own syllabus, because some schools shift the bands or drop the plus and minus grades.
Example one, a short quiz: 15 correct out of 20 questions. Divide 15 by 20 to get 0.75, multiply by 100, and the test score is 75 percent, a C on the standard scale. Example two, a class test: 42 correct out of 50 questions. Divide 42 by 50 to get 0.84, multiply by 100, and the score is 84 percent, a B. Example three, a longer exam: 89 correct out of 110 questions. Divide 89 by 110 to get 0.809, multiply by 100, and the score is 80.91 percent after rounding to two decimal places, a B minus on the plus and minus scale. Example four, using wrong answers: 4 wrong on a 25 question test means 21 correct, and 21 divided by 25 times 100 is 84 percent, a B. Each worked example follows the same three steps, so you can repeat them by hand to verify any result.
This is the question students search for most before a test, and the answer comes straight from the same formula run backwards. First find how many correct answers your passing grade percentage requires: required correct equals passing percentage divided by 100, multiplied by total questions. Then subtract that from the total to find how many questions you can miss and still pass. On a 40 question test with a 60 percent passing grade, you need 24 correct, so you can miss 16 questions and still pass. On the same 40 question test with a 70 percent passing line, you need 28 correct, so you can miss only 12. On a 25 question test with an 80 percent target, you need 20 correct, so you can miss 5. If the required number is not a whole number, round it up, because a fraction of a correct answer does not exist.
The passing grade percentage is not the same everywhere. Most high schools and colleges in the United States set the passing line at 60 percent, which is the bottom of the D band. Some programs, graduate schools, and strict instructors set it at 70 percent instead, and some international systems pass at 50 percent or even 33 percent for certain board exams. That is why a 70 percent score can be a pass with room to spare in one school and the bare minimum in another. Before you treat a result as a pass or a fail, check your course syllabus or your institution's academic rules for the exact passing grade percentage that applies to you. This calculator reports the percentage itself, which is the neutral fact every grading policy then interprets.
The same percentage logic covers tests graded by points rather than by questions. If a test is worth 50 points and you earned 43, divide points earned by points possible and multiply by 100: 43 divided by 50 times 100 is 86 percent, a B. The seed inputs on this page are correct answers and total questions, which fits any test where every question is worth the same. For a test where questions carry different point values, convert each part to points first, add up the points earned and the points possible, and apply the same formula. The result is still a percentage of correct answers in spirit: the share of the available marks you earned. Weighted course grades, where a final exam counts more than homework, are a different calculation and belong in a weighted grade calculator.
Rounding can move a grade across a boundary, so it matters. This calculator rounds to two decimal places: 80.91 percent stays 80.91, not 81. Some schools round to the nearest whole percentage, so 89.5 percent becomes 90 percent and earns an A minus on the plus and minus scale, while other schools never round up and keep 89.5 as a B+. Check your instructor's policy before assuming a rounded grade. To improve your next test score, use the percentage to find your weak spots instead of just recording the number: list the questions you missed, group them by topic, and practise that topic first. A 75 percent quiz score means one question in four went wrong, and fixing the single most repeated mistake type is usually worth more than re-reading everything. Retake a practice test under timed exam conditions, calculate the new percentage the same way, and compare it with the old one to see whether the revision worked.
Divide the number of correct answers by the total number of questions, then multiply by 100. For example, 17 correct out of 20 questions is 17 divided by 20 times 100, which is 85 percent. This is the test grade formula used by every grade percentage calculator on this page's competitor list.
First find your correct answers: correct answers equals total questions minus wrong answers. Then apply the usual formula. If you missed 4 questions on a 25 question test, you have 21 correct, and 21 divided by 25 times 100 is 84 percent, which is a B on the standard letter grade scale.
On the standard letter grade scale, A is 90 to 100 percent, B is 80 to 89 percent, C is 70 to 79 percent, D is 60 to 69 percent, and F is below 60 percent. On the plus and minus scale, A+ is 97 to 100, A is 93 to 96, A minus is 90 to 92, B+ is 87 to 89, B is 83 to 86, B minus is 80 to 82, C+ is 77 to 79, C is 73 to 76, C minus is 70 to 72, D+ is 67 to 69, D is 63 to 66, D minus is 60 to 62, and F is below 60.
In most schools it is, because the common passing grade percentage is 60 percent, so 70 percent sits above the passing line as a C minus or a C. Some programs and graduate schools require 70 percent or higher just to pass, in which case 70 percent is the bare minimum. Always check your own syllabus for the exact rule.
A 90 percent test grade is an A minus on the standard plus and minus scale, and its GPA equivalent is 3.7 on the 4.0 scale. A 93 percent or higher is a full A worth 4.0, and 97 percent or higher is an A+, also 4.0 in most systems. On the simple scale without plus and minus grades, any score from 90 to 100 percent is an A worth 4.0.
Yes, with the same maths. Divide points earned by points possible and multiply by 100. A score of 43 points out of 50 possible points is 43 divided by 50 times 100, which is 86 percent. This page asks for correct answers and total questions, so for a points based test just enter points earned as correct answers and points possible as total questions.
Multiply your passing grade percentage by the total number of questions, divide by 100, and round up to get the correct answers you need. Then subtract that from the total. On a 40 question test with a 60 percent passing grade you need 24 correct, so you can miss 16 questions and still pass. With a 70 percent passing line on the same test you need 28 correct, so you can miss 12.
This test score percentage calculator rounds to two decimal places, so 89 out of 110 questions gives 80.91 percent. Most schools round to the nearest whole percentage or to one decimal place, and some do not round at all. For example, 89.5 percent rounds up to 90 percent under nearest whole number rounding, which can change a B+ into an A minus, so check your instructor's rounding policy.
They are the same calculation with different names. A test score calculator, an exam score calculator, a quiz grade calculator, and a grade percentage calculator all divide correct answers or points earned by the total and multiply by 100. The only real differences are extra features some sites add, such as letter grade conversion, GPA equivalents, or a grade chart for teachers.
Yes. A quiz, an exam, a class test, homework, or a practice test all use the same percentage of correct answers calculation. Enter the correct answers and the total questions for that piece of work, and the result is its test score percentage. For a whole course made of several pieces with different weights, use a weighted grade calculator instead.
