What is the Exam?
The National Defence Academy (NDA) examination is the premier gateway for young aspirants to join the Indian Army, Navy, and Air Force. Conducted twice a year by the Union Public Service Commission (UPSC), the NDA exam is a two-stage selection process consisting of a written examination followed by the Services Selection Board (SSB) interview. As experts at Exam Bhai, we emphasize that the foundation batch is critical for Class 11 and 12 students, as it builds a conceptual base that is non-negotiable for clearing both the written paper and the psychological assessments at the SSB.

Foundational success is built on consistency. When searching for an affordable online coaching for NDA foundation batch, ensure the curriculum includes:

Cut-Off Trends
Historical data sourced directly from upsc.gov.in suggests that the cut-off for the written stage usually hovers between 340 and 360 marks out of 900. However, relying on the minimum cut-off is a dangerous strategy. We recommend aiming for at least 450+ to ensure a safe cushion for the final merit list, as the SSB interview adds significant variables to the final selection.
