Complete Guide to how to join Indian Army through NDA 2026

To join the Indian Army through the National Defence Academy (NDA), candidates must clear the UPSC-conducted written examination followed by the rigorous five-day Services Selection Board (SSB) interview. Eligibility requires passing Class 12, meeting strict physical standards, and qualifying for medical fitness assessments as mandated by the official UPSC notification.

What is the Exam?

The National Defence Academy (NDA) examination is a prestigious gateway for young aspirants to join the Indian Armed Forces. Conducted twice a year by the Union Public Service Commission (UPSC), it recruits candidates for the Army, Navy, and Air Force wings. For the Indian Army wing, candidates undergo intensive training at the NDA, Khadakwasla, followed by pre-commissioning training at the Indian Military Academy (IMA), Dehradun. This exam is not merely an assessment of academic knowledge; it evaluates a candidate's leadership potential, psychological stability, and physical endurance through a two-stage selection process: the objective-type written exam and the comprehensive SSB interview.

Syllabus 2026

The NDA written exam consists of two papers: Mathematics and the General Ability Test (GAT).

We at Exam Bhai emphasize that the GAT syllabus is vast. You must prioritize topics that carry the highest weightage, such as Geography and Modern History, to maximize your scoring potential.

Exam Pattern

The written examination is designed to test both depth of knowledge and speed of execution. To get a head start, you should practice free mock tests for Defence on Exam Bhai to familiarize yourself with the time-constrained environment of the paper.

Candidates must clear the sectional cut-offs for both papers. If you are struggling with the timing of these papers, we recommend that you access previous year question papers for NDA to refine your time-management skills during your revision cycle.

Consistency is the key; dedicate at least 6–8 hours daily to studies, splitting time equally between concepts and practice questions.
