What is the Exam?

The National Defence Academy (NDA) examination is a prestigious, gateway-level recruitment process conducted biannually by the Union Public Service Commission (UPSC). It selects candidates for the Army, Navy, and Air Force wings of the NDA and the Indian Naval Academy Course (INAC). For young aspirants, clearing this exam is the primary stepping stone to becoming commissioned officers in the Indian Armed Forces. The selection process is rigorous, comprising a written examination followed by the Service Selection Board (SSB) interview, which evaluates officer-like qualities (OLQs).

Preparation Strategy

At Exam Bhai, we emphasize a three-pillar strategy: Conceptual Clarity, Speed, and Analysis. First, build a solid foundation using NCERT textbooks. Second, transition to applying these concepts through our NDA mock test free online.

We recommend that you analyze every mock test you take. Do not just look at your score; identify the chapters where you lost marks due to silly mistakes versus those where you lacked conceptual understanding. By maintaining an 'Error Log,' you can track your progress over the weeks leading up to the 2026 exam.

Cut-Off Trends

Cut-off marks are determined by the UPSC and are published on upsc.gov.in after the final results are declared. Historically, for the written stage, the cut-off usually hovers between 340 to 360 marks out of 900. It is important to note that you must also secure a minimum of 25% marks in each subject individually to qualify. Trends indicate that a consistent score of 400+ in our online mocks significantly increases your probability of clearing the written stage.
