Complete Overview of the Official NDA Exam Pattern
The Union Public Service Commission (UPSC) administers the national selection test twice every year. The written exam consists of two mandatory papers conducted on a single day.
Here is the exact layout of the NDA Exam Pattern for the comprehensive written stage:
| Paper Code | Core Subjects | Number of Questions | Maximum Marks | Test Duration |
| Paper 1 | Mathematics | 120 Questions | 300 Marks | 2.5 Hours |
| Paper 2 | General Ability Test (GAT) | 150 Questions | 600 Marks | 2.5 Hours |
| Total | Written Examination | 270 Questions | 900 Marks | 5.0 Hours |
After qualifying the written cutoff, you will receive a call for the SSB Interview stage. The Services Selection Board evaluates your personality, intelligence, and officer-like traits for another 900 marks. Your final rank depends strictly on your cumulative performance across both distinct phases.
Detailed Breakdown of the NDA Marking Scheme
Understanding the official NDA marking scheme prevents you from accumulating negative marks during the exam. UPSC penalizes wrong options heavily to evaluate your accuracy levels under pressure.
- Mathematics Paper Guidelines: You get +2.5 marks for every correct choice. You lose 0.83 marks for every incorrect answer.
- General Ability Test Guidelines: You earn +4 marks for every correct answer. You lose 1.33 marks for every incorrect answer.
UPSC deducts exactly one-third of the assigned marks for every wrong response. No marks are deducted for leaving a question blank. At THE LUCKNOW CLASSES, we teach students smart elimination methods to tackle this strict NDA marking scheme safely.
