UPSC Civil Services GK Questions 2026

Static general knowledge is six of the seven lines of the General Studies Paper-I syllabus in the UPSC CSE notice: History of India and the Indian National Movement; Indian and World Geography; Indian Polity and Governance; Economic and Social Development; Environmental Ecology, Bio-diversity and Climate Change; and General Science. The Commission tests understanding rather than recall, through statements to be judged correct or incorrect, pairs to be matched and assertion-reason items, and it likes the edges of a topic: a lesser-known provision of the Constitution, a river's tributary, a species' conservation status, the mandate of a statutory body. This page holds GK24's topic-wise GK notes for UPSC, written as short facts and tables, in English and Hindi, with each note linked to the current affairs and previous-year questions on the same topic. Start with Polity and Modern History, which carry the most questions, then Geography, the Economy, Environment, Ancient and Medieval culture and Science. Read a note, solve its PYQs, take its quiz, and come back to it in your monthly revision. A candidate who knows these notes and reads the daily current affairs has covered the syllabus the notice prescribes for Paper-I.
