|---|---|---|---|---|
| 80 | 4 | 76 | 95.0% | A |
| 60 | 3 | 57 | 95.0% | A |

Formula Used Correct Answers = Total Questions − Wrong Answers Percentage = (Correct ÷ Total Questions) × 100
- 80 questions, 4 wrong
80 − 4 = 76 → (76 ÷ 80) × 100 = 95.0% → A - 60 questions, 3 wrong
60 − 3 = 57 → (57 ÷ 60) × 100 = 95.0% → A - 55 questions, 7 wrong
55 − 7 = 48 → (48 ÷ 55) × 100 = 87.3% → B - 42 questions, 9 wrong
42 − 9 = 33 → (33 ÷ 42) × 100 = 78.6% → C - 30 questions, 11 wrong
30 − 11 = 19 → (19 ÷ 30) × 100 = 63.3% → D - 18 questions, 9 wrong
18 − 9 = 9 → (9 ÷ 18) × 100 = 50.0% → F - 12 questions, 7 wrong
12 − 7 = 5 → (5 ÷ 12) × 100 = 41.7% → F
