What is the Exam?
The National Defence Academy (NDA) examination is a prestigious national-level entrance test conducted by the Union Public Service Commission (UPSC). It serves as the gateway for young aspirants to join the Indian Army, Navy, and Air Force wings of the NDA and the Indian Naval Academy Course (INAC). This exam is not merely about clearing a cutoff; it is designed to test an aspirant's mental alertness, physical fitness, and officer-like qualities (OLQs). We at Exam Bhai view the NDA exam as a transformative journey that demands a blend of academic precision and a sharp strategic mindset.

Sharma or the Pathfinder series. For GAT, supplement your reading with a daily newspaper for current affairs. We strongly recommend that you access curated study materials and practice modules for Defence exams on Exam Bhai to bridge the gap between theory and exam-readiness. Consistency in solving previous years' papers is the difference between a qualifier and a topper.
