This test grade calculator converts one assessment into a percentage and letter, then shows its effect on your course average. Count missed or correct answers when questions have equal value. Switch to points for partial credit, essays, or unequal question values. You can also compare several test percentages without combining unrelated courses.
Calculate only with inputs that match the actual grading method.
A missed true-or-false item and a missed essay cannot share one count if their point values differ. Use Points earned for mixed rubrics, deductions, or partial credit. Count-based results are appropriate only when all questions have equal value.
A percentage near a cutoff can display as the cutoff after rounding while remaining below it internally. This test grade calculator assigns the letter before display rounding. Your teacher may apply a different documented rounding rule.
If tests make up 40% of a course and four tests count equally, one test represents 10% of the course. That example assumes the other 90% is represented by your previous average. A live gradebook with ungraded categories may use a different denominator.
The worst case assumes zero on this test; the best assumes 100%. Other assignments do not change in this comparison. A 0% weight produces no movement, while a 100% weight makes this assessment the entire result.
Average tests treats each entered percentage as one equally weighted observation. It does not pool raw points. An 80% on a short quiz and a 100% on a long exam average to 90% here, regardless of their lengths.
| Letter | Minimum | GPA |
|---|---|---|
| A+ | 97% | 4.0 |
| A | 93% | 4.0 |
| A- | 90% | 3.7 |
| B+ | 87% | 3.3 |
| B | 83% | 3.0 |
| B- | 80% | 2.7 |
| C+ | 77% | 2.3 |
| C | 73% | 2.0 |
| C- | 70% | 1.7 |
| D+ | 67% | 1.3 |
| D | 63% | 1.0 |
| D- | 60% | 0.7 |
| F | 0% | 0.0 |
The standard plus/minus scale is shown here. Letter labels are references, not a substitute for your teacher’s scoring rubric or published cutoffs.
Start with the marked paper or scoring rubric. Use counts for equal questions and points for everything else.
Choose Questions missed, Questions correct, or Points earned. Enter the total available and the corresponding count or point value. The total must be positive, counts must be whole numbers, and earned credit cannot exceed the available amount.
The test grade calculator divides earned credit by possible credit and multiplies by 100. It displays one decimal place and looks up the letter using the unrounded percentage. Check the reference scale because school cutoffs may differ.
Select Course impact and enter the assessment’s effective course weight plus your average before this test. The previous average must represent the complementary share. If the test belongs inside a larger category, determine its effective weight first.
A raw score is the amount of credit earned before conversion. Texas Education Agency describes it as the number of points earned. For a classroom assessment with equal-value questions and no partial credit, counting correct answers supplies that raw score directly. A percentage places it on a common scale.
“Quizzes and narrowly limited tests in support of classroom instruction worth no more than ten percent of the semester grade may be given during the last week of classes.”
Test percentage = Earned points ÷ Possible points × 100After-test average = Previous average × (1 − Test weight) + Test percentage × Test weight. Enter weight as a percentage; the calculation converts it to a decimal.
With 20 questions and three missed answers, you earned 17 out of 20, or 85%. With 42 points earned out of 50, you earned 84%, even if the paper had only 12 questions. The test grade calculator keeps those units separate so question counts do not accidentally replace rubric points.
Course impact answers a different question. If your earlier average is 90% and this test earns 70% at a 10% course weight, the combined result is 88%. The test itself is 20 points below your previous average, but it moves the course result down only two percentage points.
This example uses Penn State’s examination policy to illustrate why assessment weight matters. Its rule permits qualifying quizzes and narrowly limited tests worth no more than 10% during the last week of classes. That is a specific scheduling rule, not evidence that every school limits every quiz to 10%.
A classroom percentage is also different from a standardized scaled score. TEA publishes conversion tables for assessment reporting; a straight percentage does not reproduce those scales. Use the official table for the applicable assessment when you need that kind of result.
The test grade calculator accepts missed answers or correct answers, so you can use whichever count appears on the paper. Both methods reach the same percentage when each question has equal value. Zero missed answers means a perfect result.
A two-point question and a ten-point essay should not count equally. Add earned points across the rubric and divide by the available points. Points mode supports decimal points without guessing how the teacher awarded partial credit.
A low score on a small quiz can have less effect than a strong score on a major exam. Compare the before and after bars, then read the highlighted difference in percentage points and the possible outcome range.
Enter percentages in chronological order to calculate an equal-weight mean. The results show the change between the first and latest scores, giving you a simple progress indicator without claiming that every intermediate result improved.
Use the result to guide a specific next step after an assessment.
Students
Use the test grade calculator to verify the arithmetic before asking about a scoring error. Compare the counted mistakes with the answer key, then switch to course impact to see whether the result materially changes your standing.
Yes. Select Questions correct and enter that count with the total. If you know only mistakes, use Questions missed. For equal-value questions, the two counts add up to the total number of questions.
Choose Points earned and sum the credit awarded by the rubric. Decimal values are accepted. The tool cannot decide how many points an explanation or partially correct solution deserves; that decision comes from the scorer.
This version limits earned credit to the total available. It does not model percentages above 100%, negative marking, curves, or bonus-point policies. Calculate those adjustments according to the instructor’s rules before interpreting course impact.
Yes. Average tests accepts a comma-separated list of percentages, oldest first. Edit the list to add or remove results. The mean uses equal weights; the trend compares only the first and latest entries.
The weight and previous average both matter. An 80% test lowers a prior 90% average but raises a prior 70% average. A larger weight magnifies either movement. The comparison bars show that direction and size together.
No. The calculations happen in your browser without submitting answers or grades. Refreshing restores the examples. Check the original paper whenever a result seems surprising, especially when switching between missed counts and earned points.
