How to Calculate Your NDA 1 2025 Score
Using the UPSC NDA 1 2025 answer key, candidates can estimate their scores based on the official marking scheme:
| Subject | Correct Answer | Incorrect Answer | Total Marks |
|---|---|---|---|
| Mathematics | +2.5 marks | -0.83 marks | 300 |
| GAT | +4 marks | -1.33 marks | 600 |
Steps to Calculate:
- Count Responses: Note the number of correct and incorrect answers for each paper.
- Apply Marking Scheme:
- Maths: (Correct × 2.5) – (Incorrect × 0.83)
- GAT: (Correct × 4) – (Incorrect × 1.33)

- Check Qualifying Marks: Ensure at least 25% (75 for Maths, 150 for GAT).
Example:
- Maths: 80 correct, 20 incorrect → (80 × 2.5) – (20 × 0.83) = 200 – 16.6 = 183.4
- GAT: 100 correct, 30 incorrect → (100 × 4) – (30 × 1.33) = 400 – 39.9 = 360.1
