How to calculate a grade out of 12
Percent = score ÷ 12 × 100
For example, 10 out of 12 is 10 ÷ 12 = 0.8333, × 100 = 83.33%, a B. Every question you miss costs 8.33 percentage points, so the gap between letters is often a single question.
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.
