Test Score Calculator Formula
Score = (Correct × Marks per Q) − (Wrong × Negative Penalty)
Worked Examples & Step-by-Step Solutions
50 Qs: 42 correct, 8 wrong (0.25 penalty)
- Positive marks: 42 × 1 = 42.
- Negative penalty: 8 × 0.25 = 2.
- Final Score: 42 − 2 = 40 out of 50 (80.00%).
- Accuracy: 42 / 50 = 84.00%.
