How to calculate a grade out of 55
Percent = score ÷ 55 × 100
For example, 44 out of 55 is 44 ÷ 55 = 0.8, × 100 = 80%, a B-. Every question you miss costs 1.82 percentage points, so the gap between letters is about 2 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.
