Grading Scale for 48 Questions
On a 48-question test, each question is worth 2.08%, so every wrong answer lowers the score by 2.08 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 48 right down to 0.
Letter grades on a 48-question test
This summary uses the standard plus/minus scale (A from 93%, A− from 90%, B+ from 87% and so on down to D− at 60%). For a plain scale, an A needs 44 right (miss up to 4), a B allows 9 misses, a C allows 14, and a D allows 19.

Borderline scores to watch
On a 48-question test, 4 scores sit just below a grade cutoff and would move up a letter grade if you round to the nearest whole percent: 43/48 = 89.6%, which rounds up to an A−; 35/48 = 72.9%, which rounds up to a C; 32/48 = 66.7%, which rounds up to a D+; 30/48 = 62.5%, 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.
Compared with a 47-question test, where each miss costs 2.13 points, a miss here costs 2.08 points, so every answer matters a little less.
