The NDA 2026 exam is a two-stage selection process comprising a written examination followed by the SSB interview. The written exam consists of Mathematics (300 marks) and General Ability Test (600 marks), totaling 900 marks. Negative marking applies, with 1/3 of the marks deducted for every incorrect response provided by candidates.
What is the Exam?
The National Defence Academy (NDA) examination is a prestigious, highly competitive national-level entrance test conducted twice annually by the Union Public Service Commission (UPSC). It serves as the gateway for young aspirants seeking admission into the Army, Navy, and Air Force wings of the NDA and the Indian Naval Academy Course (INAC). We at Exam Bhai view this as more than just a test; it is the first step toward a distinguished career as an officer in the Indian Armed Forces. The selection process evaluates candidates on their intellectual aptitude, physical fitness, and officer-like qualities (OLQs).
