The National Defence Academy (NDA) is the gateway for young aspirants who dream of serving the nation as officers in the Indian Armed Forces.

The National Defence Academy (NDA) is a premier joint training institution for future officers of the Indian Army, Navy, and Air Force. Located in Khadakwasla, Pune, NDA trains cadets in military and academic disciplines before they proceed to their respective service academies.

If you wish to serve in the Indian Armed Forces, NDA is the best opportunity after Class 12 to become an officer. The Union Public Service Commission (UPSC) conducts the NDA exam twice a year in two stages – a written exam and an SSB interview.

🔹 Total Marks: 900
🔹 Duration: 2.5 Hours for each paper

2. SSB Interview (Services Selection Board)

Candidates who clear the written exam are called for the SSB Interview, a 5-day rigorous selection process that includes:

  • Screening Test (Verbal & Non-Verbal Reasoning)
  • Psychological Tests (Thematic Apperception Test, Word Association Test, etc.)
  • Group Testing Officer (GTO) Tasks (Obstacle course, Group Discussions, Leadership Tasks)

This stage is crucial as it assesses the officer-like qualities (OLQs) in candidates, such as leadership, confidence, teamwork, and problem-solving abilities.
