Calculation breakdown
Method, assumptions and worked example
Turn missed questions into a percentage
For questions with equal value, correct answers = total questions − incorrect answers. The percentage is correct ÷ total × 100. Count unanswered questions as incorrect. For partial credit or questions with different values, switch to points and enter the total points actually awarded.
Worked example
With 20 questions and 3 incorrect, 17 ÷ 20 × 100 = 85%. At a 60% pass threshold, at least 12 correct answers are needed. The table lists every possible number missed, so teachers can reuse or print the complete marking guide.
Calculate a points-based grade
If a test awards 34.5 points out of 40, the grade is 86.25%. Do not enter the number of questions when their marks differ. This tool limits earned points to possible points; extra-credit policies need a separate adjustment.
Test percentage versus course grade
A test percentage does not determine your final course grade. A test worth 20% of a course contributes 17 percentage points when its score is 85%. Use the weighted-grade calculator for several assignments and the final-grade calculator to plan the score needed on a final exam. Letter grades and rounding policies belong to your school.
Frequently asked questions
Can I use partial marks?
Yes. Select points earned and enter decimal points, such as 34.5 out of 40.
Does 89.5% automatically become an A?
No. Letter bands and rounding vary. The tool compares the unrounded score with your entered pass threshold.
Can I print the easy-grader chart?
Yes. Calculate in equal-value questions mode, then print or download the table as CSV.
