What is the Exam?

The National Defence Academy (NDA) examination is one of the most prestigious gateway exams for students aspiring to join the Indian Army, Navy, and Air Force. Conducted twice a year by the Union Public Service Commission (UPSC), the NDA exam serves as the primary screening process for admission into the National Defence Academy and the Indian Naval Academy (INA).

We at Exam Bhai define this exam as a rigorous test of an aspirant's analytical intelligence, mathematical prowess, and general awareness. It is not merely a competitive test but a selection process that grooms the future leadership of the Indian Armed Forces. The exam consists of two stages: a written examination followed by a highly intensive Services Selection Board (SSB) interview.
