How to use this grade calculator
- 1
Enter the total number of questions (or points) on the test, quiz or assignment.
- 2
Enter the number wrong. Tap Right if you would rather count correct answers.
- 3
Read the percentage and letter grade. The chart shows the grade for every possible number wrong, so you can grade a full stack of papers without retyping.
How the grade is calculated
The score is the number correct divided by the total, times 100. For example, a 25 question quiz with 3 wrong is 22 / 25 = 0.88, which is 88%, a B+ on the US college scale.
What this grade calculator is perfect for
This grader works best on any test where every question is worth the same, so the score only depends on how many you got wrong. That covers most everyday grading:
- 01
Multiple choice (MCQ) exams
One right answer per question and one point each. Count the wrong answers, read the grade from the chart, and move to the next paper.
- 02
True or false quizzes
Fast to grade and equal weight per question, so the chart does all the math.
- 03
Bubble sheet and Scantron tests
When the scanner gives you a number wrong but no percentage, enter it here to get the percent and letter grade.
- 04
Spelling and vocabulary tests
Each word is right or wrong, which makes this the quickest way to grade a weekly word list.
- 05
Math worksheets and problem sets
Works when each problem is worth one point. Turn on half points if you give partial credit for showing work.
- 06
Pop quizzes and exit tickets
Short checks of 5 to 10 questions where you want a grade in seconds, not a spreadsheet.
- 07
Points based assignments
Enter total points instead of questions and points lost instead of number wrong. A 50 point lab report with 6 points off is 88%.
- 08
Practice and mock exams
Students can check a result on SAT, ACT, GRE, IELTS, driving theory or certification practice tests and see how many more they need right to reach the next grade.
- 09
Language and flashcard drills
Self graded rounds of 20 or 50 cards, to track progress from one session to the next.
Who uses it

Grading a stack of papers, they use the chart like a printed EZ grader: find the number wrong, write down the score.
Teaching assistants
Keep grades consistent across sections.
Students
Work out a test score from the number wrong, or see how many mistakes they can afford and still pass.
Parents and homeschoolers
Grade home tests and worksheets.
When to use a different calculator
This tool assumes every question has the same value. If your course grade mixes parts with different weights, for example homework 20%, midterm 30% and final exam 50%, you need a weighted grade calculator instead. The same goes for tests where some questions are worth more than others: add up the points and use points mode, rather than counting questions. And if your teacher grades on a curve, your letter grade also depends on how the rest of the class did, so read how grading on a curve works.

How do I grade a multiple choice exam?
Enter the number of questions on the exam, then count the wrong answers on each paper. The chart lists the score for every possible number wrong, so you can grade a whole class by reading one row per paper.
Can I grade tests worth points instead of questions?
Yes. Enter total points in the first box and points lost in the second. Turn on half points if your test gives partial credit.
What is the US college grading scale?
Most US colleges use plus and minus letter grades on a 4.0 GPA scale: A = 93% and up, A- = 90%, B+ = 87%, B = 83%, B- = 80%, and so on down to D- = 60%. Below 60% is an F. A D- is usually the lowest passing grade, but many majors require a C or better. Cutoffs vary by school, so you can edit them above. Our guide to how US college grading works covers plus and minus grades, GPA and pass/fail in more detail.
