Cracking the NDA in your first attempt requires a disciplined integration of conceptual clarity in Mathematics, high-proficiency in General Ability, and rigorous physical conditioning. Success is achieved by mastering the UPSC syllabus, strictly adhering to time-bound mock practice, and maintaining unwavering consistency in your daily study routine for both written and SSB.
What is the Exam?
The National Defence Academy (NDA) examination is one of the most prestigious competitive exams in India, conducted biannually by the Union Public Service Commission (UPSC). It serves as the gateway for young aspirants to join the Army, Navy, and Air Force wings of the NDA and the Indian Naval Academy Course (INAC). We at Exam Bhai believe that the NDA is not merely an exam but a selection process designed to evaluate your intellectual prowess, psychological fitness, and leadership potential. The process is divided into two primary stages: a written examination consisting of Mathematics and General Ability Test (GAT), followed by the rigorous five-day Services Selection Board (SSB) interview.
Key Highlights 2026
Staying updated with the latest exam cycle is crucial for first-time aspirants. For 2026, the process remains highly competitive. The selection is based on a merit list prepared by the UPSC, considering the cumulative marks obtained in the written exam and the SSB interview. Candidates must clear the individual sectional cut-offs in both subjects to qualify for the next stage.
