How to calculate a grade out of 24
Percent = score ÷ 24 × 100
For example, 19 out of 24 is 19 ÷ 24 = 0.7917, × 100 = 79.17%, a C+. Every question you miss costs 4.17 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.
