How to work it out
5 ÷ 10 = 0.5
0.5 × 100 = 50%
Divide the score by the total, then multiply by 100. 5 out of 10 means you got 5 of 10 right and missed 5, so each question is worth 10%.
6 out of 10 (60%) would move you up to a D−.
Every score out of 10
| Score | Percent | Letter grade |
|---|---|---|
| 10 out of 10 | 100% | A |
| 9 out of 10 | 90% | A− |
| 8 out of 10 | 80% | B− |
| 7 out of 10 | 70% | C− |
| 6 out of 10 | 60% | D− |
| 5 out of 10 | 50% | F |
| 4 out of 10 | 40% | F |
| 3 out of 10 | 30% | F |
| 2 out of 10 | 20% | F |
| 1 out of 10 | 10% | F |
| 0 out of 10 | 0% | F |
Letter grades use the common US scale (93 and up is an A, 90–92 an A−, and so on, below 60 an F). Your school or teacher may use a different one.
