NDA Exam 2026: The Selection Process

So, you’ve checked that you meet the eligibility requirements. Now, let’s dive into the selection process. The NDA exam follows a two-stage process: the written exam and the SSB interview.

  1. Written Examination:
    The written exam is the first hurdle you need to clear. It consists of two papers:

Mathematics (Paper 1): This paper tests your knowledge of mathematics at the Class 12 level. Topics include algebra, calculus, trigonometry, geometry, statistics, and more.

General Ability Test (GAT) (Paper 2): This paper has two sections:
