Test Grade Calculator

Divide your correct answers by the total number of questions, then multiply by 100. That gives your test percentage. For example, 36 correct out of 45 questions = 80% (a B). This test grade calculator does the math instantly. Enter your numbers and your percentage, letter grade, and GPA appear right away.

Select Marks Mode, enter your total marks and the marks you earned. The formula is: (marks earned ÷ total marks) × 100. So 72 points out of 90 = 80%. This makes the calculator work as a test grade calculator for points-based exams, not just question-counted ones.

Your grade percentage = (correct answers ÷ total questions) × 100. On a 50-question test, getting 43 right = 86%. The calculator also shows this as a letter grade and GPA so you don’t have to do any extra conversion yourself.

Subtract the number of correct answers required to pass from the total questions. On a 40-question test with a 60% passing threshold, you need 24 correct — meaning you can miss 16. Enter your total in the What-If tool and adjust the correct answer count until you hit the pass line. It shows you exactly where your cutoff is.

Enter your total questions and your target percentage into the Target Grade Predictor. It calculates the minimum correct answers needed. For a 25-question test at 70%, you need at least 18 correct. No manual calculation required.

Once you calculate your score, the results panel shows “You missed X questions” automatically. You can also subtract your correct answers from total questions: 50 total − 38 correct = 12 wrong. The Smart Insights panel breaks this down clearly after every calculation.

Use the What-If simulation. Enter your total questions, then use the +/− buttons to adjust correct answers up or down. Your updated percentage and letter grade refresh instantly. It’s the fastest way to see what will my grade be before results are officially returned.

The Smart Insights panel shows you the exact percentage value of each question. On a 20-question test, each wrong answer costs you 5%. Use the What-If tool to see how much your grade drops question by question. There’s no guessing — the number updates live.

Enter 15 in the Total Questions field and your correct answers in the second field. The calculator converts any score out of 10, 15, 20, 30, 40, 50, 60, 75, or 100 into a percentage and letter grade instantly. It works for any total, not just standard sizes.

It works the same way for exams as for tests. Enter total exam questions (or total exam points in Marks Mode) and the number you got right. Your exam grade — percentage, letter, and GPA appears immediately. Teachers can also use it as a quick exam grader to check student scores one at a time.

Yes. Enter total quiz questions and correct answers. It calculates your quiz grade percentage and letter grade the same way it handles full exams. For grading an entire class’s quizzes at once, the Class Grader Calculator handles batch scoring more efficiently.

The formula is: (correct answers ÷ total questions) × 100 = your grade percentage. Enter both numbers here and the percentage score calculator does it automatically. You’ll also get the letter grade and GPA without any extra steps.

A test score converter turns a raw score (like 34/40) into a percentage, letter grade, and GPA. This calculator does all three conversions at once. Enter any raw score and it converts it into a standardized result you can compare against grading scales.

Enter the total questions on your test and how many you answered correctly. Your grade appears instantly. If you want to see what score you need on a future test, use the Target Grade Predictor. Just enter your desired percentage and it shows the correct answer count required to reach it.

Teachers enter total questions and a student’s correct answers to get an instant percentage and letter grade. It works as a teacher grader for any single test, quiz, or exam and no spreadsheet needed. For grading an entire class, the Teacher Grader and Class Grader are built for that.

Enter your total in the Total Questions field and your correct answers. The calculator generates the grading scale for that exact question count and shows your percentage and letter grade. It handles any test length automatically, so there’s no fixed scale to look up.

Most US schools set passing at 60% (a D). Some set it at 70% (a C). Enter your numbers and the Smart Insights panel will tell you exactly whether you passed and by how much. The Grade Chart inside the calculator shows the full percentage range for every letter grade from A to F.

Enter total questions and correct answers. Your score appears instantly as a percentage, letter grade, and GPA. If you only know your points (e.g., 54/75), switch to Marks Mode and enter those numbers instead. It works as a score checker for any question count or point total.

For a single test within a class, yes. Enter that test’s questions and correct answers. For calculating your overall class grade across multiple assignments and tests, the Syllabus Grade Calculator handles weighted scoring across every assessment category. Teachers grading multiple students should use the Class Grader, which is built for batch scoring an entire class at once.

On the standard US grading scale: A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, F = below 60%. The calculator assigns these automatically. For a full explanation of what each letter grade signals academically, see what do letter grades really mean.

Enter total questions once, then update the correct answer field for each student. Each result takes under three seconds. For grading papers in bulk, how to grade an entire class in 15 minutes covers the fastest workflows teachers use. You can also compare easy grader vs manual grading to see which saves the most time for your setup.

Your raw score (e.g., 38/50) and your grade percentage (76%) are different ways of expressing the same result. This calculator converts raw scores into percentages automatically. If your percentage doesn’t match what your teacher marked, it may be because partial credit or curved grading was applied. This score calculator uses only standard straight‑percentage grading, without curves or adjustments.

Yes. 27 out of 40 = 67.5%, which is a D on the standard grading scale — above the 60% passing threshold. To calculate it: 27 ÷ 40 × 100 = 67.5%. Enter 40 in Total Questions and 27 in Correct Answers above to confirm and see the full grading chart for a 40-question test.

A 67% is a D on the standard US grading scale (60–69% = D, GPA 1.0). It is a passing grade in most schools, but below average. On a 100-question test, 67% means you got 67 correct and missed 33. On a 30-question test, 67% is approximately 20 correct answers.

75 out of 100 = 75%, which is a C (70–79% range, GPA 2.0). It is a passing grade. Teachers sometimes refer to this as an average score, meeting the standard but with clear room to improve.

A 63% is a D on the standard grading scale (60–69% range, GPA 1.0). It is technically passing in most US schools where 60% is the minimum. On a 40-question test, 63% means approximately 25 correct answers. Use this calculator to find the exact number for any test size.

No. In most US schools, 60% is the minimum passing grade (a D, GPA 1.0). Scoring exactly 60% means you passed, but only just. Some schools and teachers set their passing threshold at 65% or 70%, so check your syllabus. To understand how grading thresholds are set in your school, syllabus grading breakdown explains it clearly.

No. A 3.5 GPA sits between a B and an A on the standard 4.0 scale — it corresponds to roughly 85–89%, not 75%. On the standard scale: 4.0 = 90–100% (A), 3.0 = 80–89% (B), 2.0 = 70–79% (C). A 75% converts to a C, which equals a 2.0 GPA. For a full breakdown of GPA conversion, the 7 simple steps to calculate high school GPA are helpful.

On a standard 40-question test: 36–40 correct = A (90–100%), 32–35 = B (80–89%), 28–31 = C (70–79%), 24–27 = D (60–69%), 23 or below = F (below 60%). Enter 40 in the Total Questions field above and the calculator generates the complete grading scale for every possible score automatically.

On a 30-question test: 27–30 correct = A, 24–26 = B, 21–23 = C, 18–20 = D, 17 or below = F. Each question is worth 3.33%. Enter 30 in Total Questions above to see the full dynamic chart for this test size.

On a 50-question test: 45–50 correct = A, 40–44 = B, 35–39 = C, 30–34 = D, 29 or below = F. Each question is worth exactly 2%. Enter 50 in Total Questions to generate the complete grading scale instantly.

Divide correct answers by total questions and multiply by 100. Formula: (correct ÷ total) × 100 = percentage. For 34 correct out of 50: 34 ÷ 50 × 100 = 68% (D). This calculator does that instantly for any score — by questions answered or by points earned.
