How to calculate a grade out of 33
Percent = score ÷ 33 × 100
For example, 26 out of 33 is 26 ÷ 33 = 0.7879, × 100 = 78.79%, a C+. Every question you miss costs 3.03 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.
