Calculate exam score from correct/incorrect answers or raw points. Supports wrong-answer penalty (negative marking) for competitive exams.

The Exam Score Calculator converts your raw exam performance into a percentage and letter grade. It supports two modes: By Questions (number correct out of total, with optional wrong-answer penalty) and By Points (raw score out of total possible points). Use the penalty mode for standardized tests like the SAT or tests with negative marking.
Use the Questions mode for multiple-choice exams where every question is worth one point. Use the Points mode for exams that mix question types — for example, where short answer questions are worth 5 points each and essay questions are worth 25 points each.
There is no single universal answer, because it depends on the exam's difficulty and the class average. A 70% on a notoriously hard organic chemistry exam may place you above the class average. An 85% on an easy intro course exam may be below average. Exam scores need context to be meaningful.
As a general benchmark on the US grade scale: 90%+ is excellent, 80–89% is good, 70–79% is average, and 60–69% is below average. Below 60% is typically a failing score, though course minimums vary.
One exam score rarely makes or breaks a course grade unless the exam carries heavy weight. To see the full impact on your final course grade, take your exam score result and enter it into the Weighted Grade Calculator alongside your other assessments and their respective weights.
If your exam was the final and you want to know whether you hit your target course grade, use the Final Grade Calculator. Enter your pre-final course grade, the final exam score you just calculated, and the exam's percentage weight to see your overall result.
To find the maximum number of questions you can get wrong and still pass, use the reverse calculation: multiply the total questions by the passing percentage. For a 50-question exam with a 70% passing threshold, you must answer at least 35 correctly — meaning you can miss no more than 15.
This calculation assumes all questions are worth equal points. If your exam uses variable point values, enter total points earned and total points possible in the Points mode instead.
