NDA Exam Pattern 2026: Understanding the Structure

The NDA exam pattern is straightforward but requires strategic preparation. The exam consists of two main parts:

  1. Written Exam: This is an objective-type test with two papers:
    • Mathematics (300 marks, 2.5 hours)
    • General Ability Test (GAT) (600 marks, 2.5 hours)

    The GAT is further divided into two parts: English and General Knowledge. Negative marking applies to incorrect answers, so accuracy is crucial.

  2. SSB Interview: Candidates who clear the written exam are called for the SSB (Services Selection Board) interview. This is a comprehensive assessment of your personality, intelligence, and aptitude for leadership. It’s a multi-day process involving psychological tests, group discussions, interviews, and physical tasks.
