How to Calculate Your Marks Using the Answer Key
Follow these steps:
- Match each answer against the official key for your series.
- Count the correct answers.
- Count the wrong answers.
- Apply the formula below.
Total Score = Number of Correct Answers − (Number of Wrong Answers ÷ 3)
Example: If you answered 70 questions correctly and 18 incorrectly, and left 12 unanswered:
- Correct: 70 × 1 = 70
- Negative marks: 18 ÷ 3 = 6
- Final score: 70 − 6 = 64 marks
This gives only an estimate. Kerala PSC will publish the final result and rank list separately.
