1. NDA Exam Pattern & History Weightage Analysis

In the UPSC NDA General Ability Test (GAT), History forms a crucial part of Section B (General Knowledge). Historical questions consistently account for roughly 12 to 15 questions, translating to 48–60 marks out of the total 600 in GAT. The UPSC pattern heavily prioritizes chronological sequences, administrative terminology (e.g., Mansabdari system, Dhamma, revenue policies), major treaties, and leadership in anti-colonial uprisings. Analyzing previous years' questions (PYQs) reveals that Modern History dominates with ~60% weightage, followed by Ancient (~20%) and Medieval (~20%).
