How to Use the Test Grade Calculator

Enter the number of questions you answered correctly and the total number of questions in the Score tab above to get your percentage and letter grade instantly. Switch to Curve to factor in bonus points — enter your raw score, the curve points your teacher is adding, and the total possible to see both raw and curved grades side by side.

The Advanced calculator below adds multi-test tracking and grade trend analysis. For full batch grading with statistics and curve comparison, scroll to the Professional tier.

Score & Curve Formulas

Score % = (Questions Correct ÷ Total Questions) × 100

Curved Score = Min(Raw Score + Curve Points, Total Possible)
Curved % = (Curved Score ÷ Total Possible) × 100

Grade Scale Reference

A+ 97–100% | A 93–96% | A- 90–92% | B+ 87–89% | B 83–86% | B- 80–82%
C+ 77–79% | C 73–76% | C- 70–72% | D+ 67–69% | D 63–66% | D- 60–62% | F 0–59%

Worked Example

Test: You got 38 out of 45 questions correct. Your teacher curves by 5 points.

Raw: (38/45) × 100 = 84.44% (B)

Curved: (43/45) × 100 = 95.56% (A)

The 5-point curve improved your grade by over 11 points and moved you from a B to an A!

Frequently Asked Questions

If questions have different point values, use the Points tab of the Grade Calculator instead. Enter each question or section as a separate row with its earned points and total possible points. That calculator handles unequal point values correctly.

There are many types of curves. This calculator uses the most common: adding a fixed number of points to everyone's raw score. Other types include scaling so the highest score becomes 100%, or adding a percentage to everyone's final grade. Always confirm which method your teacher uses.

This calculator caps the curved score at the total possible (so the percentage maxes out at 100%). In real classes some teachers do allow scores above 100% as extra credit, but the standard interpretation keeps the ceiling at 100%.

To find the minimum correct answers for a target grade, multiply the target percentage by the total questions and divide by 100. For example: to get 90% on a 45-question test you need at least 90% × 45 ÷ 100 = 40.5 → 41 correct answers.

Yes, this calculator uses the standard +/- grading scale: A+ starts at 97%, A at 93%, A- at 90%, B+ at 87%, and so on down to F below 60%. If your school uses a different scale, use the letter grade as a general guide and confirm with your specific grading policy.
