How it works

Correct answers divided by total questions gives your percentage. That percentage maps to a letter grade on the standard scale. If your test deducts points for wrong answers, enter the per-question penalty and the calculator adjusts the score.

Grading scales vary: this calculator uses a common US plus/minus scale. Your school or instructor may use different cutoffs. Check your syllabus before drawing conclusions.
