Static GK decides the General Awareness score in SSC CGL. Of the 25 questions in Tier-I and the 25 in Tier-II Paper-I, most come from Indian Polity, History, Geography, the Economy and General Science, the areas the CGL 2026 notice lists as History, Culture, Geography, Economic Scene, General Policy and Scientific Research relating to India and its neighbouring countries. Polity questions ask about articles, parts and schedules of the Constitution, amendments, the President, Parliament, the Supreme Court and constitutional bodies. History covers the Indus Valley, the Mauryas and Guptas, the Delhi Sultanate and Mughals, and the freedom struggle from 1857 to 1947. Geography asks about rivers, soils, climate, national parks, minerals and world physical features. The Economy part asks about budget terms, the RBI, banking and basic concepts. General Science is school-level Physics, Chemistry and Biology. This page holds GK24's topic-wise GK notes for SSC CGL, written as short facts and tables so a topic can be revised in one sitting. Read a topic, then solve its previous-year questions and quiz on this site to check what you retained.
