NDA Exam Overview 2026

The National Defence Academy (NDA) exam, conducted by the Union Public Service Commission (UPSC), is the gateway to prestigious careers in the Indian Army, Navy, and Air Force. For 2026, the exam follows the established pattern with two sessions: NDA 1 (likely in April) and NDA 2 (likely in September). Each features a written test followed by the Services Selection Board (SSB) interview.

The written exam comprises two papers: Mathematics (Paper 1, 300 marks, 120 questions, 2.5 hours) and General Ability Test (GAT, Paper 2, 600 marks, 150 questions, 2.5 hours). Negative marking applies (one-third deduction for wrong answers), emphasizing accuracy over guesswork. Qualifying candidates proceed to SSB, which assesses officer-like qualities through psychological tests, group tasks, and interviews.

Eligibility remains standard: unmarried males/females aged 16.5–19.5 years, with 10+2 qualification (or appearing). For Air Force and Navy, Physics, Chemistry, and Maths in 10+2 are mandatory. The total vacancies are around 400–450 annually, making competition intense. Preparation should start early, ideally in Class 11, focusing on conceptual understanding rather than rote learning.

GZDA’s approach integrates this overview into our coaching, where we simulate exam conditions to build resilience. Aspirants should note that while the syllabus hasn’t seen major changes, staying updated via the official UPSC website is crucial. This ensures your NDA preparation books align with the latest requirements.

Books to Avoid

Ignore overly complex advanced texts if basics are weak— they confuse beginners. Reason: Building from NCERT prevents foundational gaps.

Avoid unverified self-published or hype-driven new launches without long-term reviews. Reason: Credibility comes from consistent use in academies, not marketing.

Strategy for Maths: Read NCERT theory, solve Aggarwal examples, then Arihant mocks. Revise weekly, tracking errors in a notebook. Practice under timed conditions.

For GAT: Build English via daily Wren & Martin exercises. For GK/Science, read NCERT chapters, summarize key facts. Use Lucent for revision, Manorama for monthly current affairs. Polity: Focus on Laxmikanth’s core chapters.
