CDS 2 2025 Marking Scheme & Score Calculation
The CDS exam follows a negative marking system. The score is calculated using this formula:
CDS Score=C−0.33×W
CDS Score=C−0.33×W
Where:
- C
- C = Number of correct answers
- W
- W = Number of wrong answers
Key Points:
- Each correct answer gives +1 mark.
- Each wrong answer deducts 0.33 marks.
- No marks are deducted for unattempted questions.
- Each section carries a maximum of 100 marks.
Example: If a candidate answered 70 questions correctly and 20 incorrectly, the score would be:
- Marks=70−(0.33×20)=70−6.6=63.4
- Marks=70−(0.33×20)=70−6.6=63.4
