Grading Scale for 80 Questions

On a 80-question test, each question is worth 1.25%, so every wrong answer lowers the score by 1.25 percentage points. That is typical of a final exam or a long practice test. The chart below shows the percentage and letter grade for every possible score, from 80 right down to 0.

Borderline scores to watch

On a 80-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: 74/80 = 92.5%, which rounds up to an A; 66/80 = 82.5%, which rounds up to a B; 58/80 = 72.5%, which rounds up to a C; 50/80 = 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.

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 75-question test, where each miss costs 1.33 points, a miss here costs 1.25 points, so every answer matters a little less.
