Which NCERT Books are Required for UPSC Prelims and Mains, and How Should I Study Them?

What are the best NCERT books for UPSC Prelims and Mains- is this the same question you have been hooked to? Important NCERT books for both levels of the exam span Class 6 through 12, covering core subjects such as History, Geography, Polity, Economics, Science, and Indian Society. Class 6 to 12 NCERT books for UPSC are meant for different stages of preparation and treated as the standard foundation for the Prelims General Studies paper and Mains GS Papers 1, 2, and 3. Along with the relevant textbooks, resources such as Oswaal NCERT One For All for UPSC can support revision and practice. A subject-wise book list and structured study plan can help you prioritise important topics and prepare more effectively for both stages of the examination.

Not every class carries equal weight. Classes 6 to 10 are best for building basics, especially in History, Science, and introductory Economics, and beginners should read them at least once before moving to advanced books. Classes 11 and 12 matter most for Polity, Geography, and Economy, since they cover the core concepts UPSC tests repeatedly, such as the Constitution, physical and human geography, and macroeconomics. Society-related topics for GS I directly pop up from the Class 11 and 12 Sociology textbooks, while Environment and Ecology are covered through Geography and Class 12 Biology chapters.
