What is the Exam?

The National Defence Academy (NDA) examination is a prestigious national-level entrance test conducted twice a year by the Union Public Service Commission (UPSC). It serves as the gateway for 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 not just as an exam, but as a gateway to a life of honor and service. The written examination tests a candidate's aptitude in Mathematics and General Ability, followed by the rigorous Services Selection Board (SSB) interview process.
