Static general knowledge fills most of Paper-I in UPSC CAPF. Of the six areas the CAPF (ACs) 2026 notice lists for General Ability and Intelligence, four are static: General Science; Indian Polity and Economy; History of India; and Indian and World Geography. The notice's wording shows the depth expected. Polity covers the political system and the Constitution of India, social systems, public administration, security issues and human rights with their indicators. Economy covers economic development in India. History covers social, economic and political aspects, including the growth of nationalism and the freedom movement. Geography covers physical, social and economic aspects of India and the world. General Science asks about everyday scientific phenomena and new areas such as Information Technology, Biotechnology and Environmental Science.

The same notes serve Paper-II, whose essay part suggests modern Indian history, the freedom struggle, geography, polity and economy as topics. Read one topic at a time, then solve its quiz and the CAPF previous-year questions on this site to check what you have retained.
