Grading Scale for 42 Questions

On a 42-question test, each question is worth 2.38%, so every wrong answer lowers the score by 2.38 percentage points. That is typical of a unit test or midterm. The chart below shows the percentage and letter grade for every possible score, from 42 right down to 0.

Borderline scores to watch

On a 42-question test, 3 scores sit just below a grade cutoff and would move up a letter grade if you round to the nearest whole percent: 39/42 = 92.9%, which rounds up to an A; 28/42 = 66.7%, which rounds up to a D+; 25/42 = 59.5%, which rounds up to a D−. Decide your rounding rule before grading so these students are treated the same way. The EZ Grader’s Show decimals option shows the exact value.

Need a different grade scale, half points or bonus questions? The EZ Grader rebuilds this chart with your school’s cutoffs, Class Mode grades a whole class list at once, the grade chart library compares test sizes side by side, and the same grade calculator works out weighted and final grades.

Compared with a 41-question test, where each miss costs 2.44 points, a miss here costs 2.38 points, so every answer matters a little less.
