Marking Scheme and Score Calculation
Each correct answer gives one mark, and each wrong answer cuts 0.33 mark. Unanswered questions have no marks. Final score is calculated by adding all correct marks and subtracting the penalty for wrong answers. This helps you know your expected score.
- Correct Answer: +1 mark
- Incorrect Answer: –0.33 mark (1/3rd negative marking)
- Unattempted: 0 mark
Final Score Formula:
Total Marks = (Number of Correct Answers × 1) – (Number of Incorrect Answers × 0.33)
Example: If a candidate answers 75 questions correctly and 15 incorrectly, the score will be:
(75 × 1) – (15 × 0.33) = 75 – 4.95 = 70.05 marks.
