How to calculate a grade out of 27
Percent = score ÷ 27 × 100
For example, 22 out of 27 is 22 ÷ 27 = 0.8148, × 100 = 81.48%, a B-. Every question you miss costs 3.7 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.
