What is the Exam?

The National Defence Academy (NDA) examination is a prestigious national-level recruitment process conducted by the Union Public Service Commission (UPSC) to induct candidates into the Army, Navy, and Air Force wings of the Indian Armed Forces. As the premier tri-service academy in Khadakwasla, Pune, the NDA serves as the foundational training ground for future leaders. We at Exam Bhai believe that understanding the nuances of the selection process—which includes a rigorous written exam and the Service Selection Board (SSB) interview—is the first step toward securing your commission as an officer.

Cut-Off Trends

Historical trends published on the UPSC official portal indicate that the qualifying marks for the written examination typically hover between 320 to 360 marks out of 900.
