Enter the number of questions and number of wrong answers to get your test grade as a percentage, letter grade, and fraction. You can also choose between grading scales — standard (A, B, C, D, F) or plus/minus (A+, A, A−, B+, ...) — to match your school's system.

Divide the number of correct answers by the total number of questions, then multiply by 100. For example, if you got 32 out of 40 correct, your score is (32 / 40) × 100 = 80%, which is a B on a standard grading scale.
The standard scale uses broad letter grades: A (90–100%), B (80–89%), C (70–79%), D (60–69%), and F (below 60%). The plus/minus scale breaks each letter into three tiers — for example, A+ (97–100%), A (93–96%), and A− (90–92%) — giving a more precise indication of performance.
Yes. 27 out of 40 equals 67.5%, which typically corresponds to a D+ on a plus/minus scale or a D on a standard scale. While it is technically passing in most schools, it is considered below average.
If you got 7 wrong out of 40, you answered 33 correctly, giving you a score of (33 / 40) × 100 = 82.5%. On a standard scale that is a B, and on a plus/minus scale it is a B−.
Yes. 75 out of 80 equals 93.75%, which is an A on both the standard and plus/minus grading scales. On the plus/minus scale it falls precisely into the A range (93–96%).
In most educational systems, a passing grade starts at 60%, which corresponds to a D on a standard scale. However, individual schools or courses may set a higher passing threshold, sometimes 65% or 70%, so always check your institution's policy.
Yes. Simply enter the total number of questions and set wrong answers to (total − correct). For example, if you got 35 right out of 50, enter 50 total questions and 15 wrong answers to get your grade.
On the standard scale: A = 90–100%, B = 80–89%, C = 70–79%, D = 60–69%, F = below 60%. The plus/minus scale further divides these, for instance B+ = 87–89%, B = 83–86%, B− = 80–82%.
