Grading Scale for 100 Questions
On a 100-question test, each question is worth 1%, so every wrong answer lowers the score by 1 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 100 right down to 0.
Letter grades on a 100-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 90 right (miss up to 10), a B allows 20 misses, a C allows 30, and a D allows 40.

|---|---|---|---|
| A+ | 97–100 | 0–3 | 97–100% |
| A | 93–96 | 4–7 | 93–96% |
| A− | 90–92 | 8–10 | 90–92% |
| B+ | 87–89 | 11–13 | 87–89% |
| B | 83–86 | 14–17 | 83–86% |
| B− | 80–82 | 18–20 | 80–82% |

| C | 73–76 | 24–27 | 73–76% |

| D+ | 67–69 | 31–33 | 67–69% |
| D | 63–66 | 34–37 | 63–66% |
| D− | 60–62 | 38–40 | 60–62% |
| F | 0–59 | 41–100 | 0–59% |

Borderline scores to watch
No score on a 100-question test rounds up into a higher letter grade, so your rounding policy never changes a grade on a test this size (standard plus/minus scale).
Compared with a 90-question test, where each miss costs 1.11 points, a miss here costs 1 points, so every answer matters a little less.
