How to calculate a grade out of 100

Percent = score ÷ 100 × 100

For example, 80 out of 100 is 80 ÷ 100 = 0.8, × 100 = 80%, a B-. Every question you miss costs 1 percentage points, so the gap between letters is about 3 questions.

Letters follow the standard U.S. plus/minus grading scale. If your teacher uses different cutoffs (like 93/85/77/70), build a custom chart with the EZ Grader. For a single score, the test grade calculator is quickest.
