Complete Guide to best books for NDA exam history and geography 2026

For candidates aiming to ace the NDA 2026 General Ability Test (GAT), the most effective resources for History and Geography are NCERT textbooks (Classes 6-12) for conceptual foundation, complemented by a dedicated 'General Studies' manual or subject-specific capsules for concise revision, and consistent practice of previous year questions (PYQs).

What is the Exam?

The National Defence Academy (NDA) examination is a prestigious, biannual competitive test conducted by the Union Public Service Commission (UPSC) to select officer cadets for the Indian Army, Navy, and Air Force. As we at Exam Bhai observe, it is not merely a test of academic knowledge but an assessment of a candidate’s potential to demonstrate officer-like qualities (OLQs) under pressure. The exam is divided into two primary stages: a rigorous objective-type written examination and a comprehensive Service Selection Board (SSB) personality interview.

2. Advanced Reference: Use specialized defence-oriented manuals like 'Disha Defender' or 'PW ShauryaVeer' to streamline your notes.
