An exam percentage calculator turns the number of correct answers and the total questions into a percentage score, a letter grade and a count of mistakes — handy for marking tests and quizzes.
Letter grades use common bands: A (90+), B (80–89), C (70–79), D (60–69), F (below 60).
The bands shown are a common US-style scale. Your school or country may use different thresholds, so always check the official grading scheme.
Enter the equivalent whole number of correct questions. For weighted or partial-credit papers, convert marks to a fraction of the total first.
