How to Calculate NDA 2 2025 Score

To calculate the NDA 2 2025 score for each paper, follow the following formula: 

Final Score = (Correct Answers × Marks Per Question) – (Wrong Answers × Negative Marks)

Example:

Suppose you attempted:

Mathematics:

• Correct: 70

• Wrong: 30

• Unattempted: 20

Score = (70 × 2.5) – (30 × 0.83) = 175 – 24.9 = 150.1

GAT:

• Correct: 90

• Wrong: 40

• Unattempted: 20

Score = (90 × 4) – (40 × 1.33) = 360 – 53.2 = 306.8

Total NDA Score = 150.1 + 306.8 = 456.9 / 900

Conclusion
