How to calculate a grade out of 42
Percent = score ÷ 42 × 100
For example, 34 out of 42 is 34 ÷ 42 = 0.8095, × 100 = 80.95%, a B-. Every question you miss costs 2.38 percentage points, so the gap between letters is about 1 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.
