What is NDA? The Gateway to Becoming an Officer

Simply put, NDA stands for National Defence Academy. It’s a world-renowned, tri-service academy (meaning it trains for Army, Navy, and Air Force together) located in Khadakwasla, Pune, Maharashtra.

The aim is to instill qualities of leadership, discipline, physical fitness, and mental toughness. It’s a place where cadets not only get military training but also complete their graduation degree (B.A., B.Sc., or B.Tech from Jawaharlal Nehru University, Delhi).
