1. NDA Selection Process Overview

The NDA selection process is divided into two main stages:

1. Written Examination
2. Service Selection Board (SSB) Interview

Stage 1: Written Examination

The first step is a written examination conducted by the Union Public Service Commission (UPSC). This exam assesses the candidate’s academic knowledge, logical reasoning, and aptitude.

Stage 2: SSB Interview

Those who qualify the written exam are called for the SSB Interview, which is a multi-day assessment that evaluates personality traits, leadership skills, and physical fitness. The SSB process also includes various physical and psychological tests.

Stage 3: Medical Examination

Candidates clearing the SSB are then required to pass a comprehensive medical examination to ensure they meet the physical and medical standards required for the Armed Forces.

2. NDA Exam Pattern

The NDA written examination is divided into two papers:

• Mathematics (300 marks)

5. Final Selection and How Many Candidates Are Selected

The final merit list is prepared based on the combined scores of the written exam and the SSB interview, which carry equal weight (900 marks each). The number of candidates selected depends on the number of vacancies, which typically range between 350-400 per batch, across all three services (Army, Navy, and Air Force).

Candidates need to secure a place in the merit list to be admitted to the NDA. The overall selection ratio is quite low, with only a fraction of the initial applicants making it to the final merit list.

6. Essential Points for NDA Aspirants

• Consistency in Preparation: The NDA exam requires focused and disciplined preparation. Cover all sections of the syllabus, especially mathematics, and focus on building general awareness.
• Physical Fitness: Start preparing for the physical fitness tests early, as they are crucial during the SSB process.

• Improve Communication Skills: The SSB interview process involves group discussions and personal interviews, where good communication skills play a vital role.
• Be Aware of Current Events: Stay updated with national and international news for the General Knowledge section.
• Confidence and Leadership: SSB tests your leadership qualities and ability to work in a team. Practice group activities and develop leadership qualities.
