Grading Scales by Number of Questions
Pick your test length to see the percent and letter grade for every score.
Every chart here uses the same standard plus/minus scale: A- at 90%, B- at 80%, C- at 70% and D- at 60%, and anything lower is an F. Each tile shows how many right answers that test needs for an A- or better. The shorter the test, the more each question is worth: 20 points on a 5-question test, 1 point on a 100-question test.
