Static GK carries most of the 100 marks of the CDS General Knowledge paper. Of the 120 questions in the CDS (II) 2026 paper, about 20 were on Indian Polity, about 20 on the History of India, about 15 on Geography and the environment, about 10 on the Indian Economy and about 37 on Physics, Chemistry and Biology, which makes CDS the most science-heavy General Knowledge paper among the major recruitment exams. Polity questions test writs, the NHRC, electoral systems, disqualification of legislators, GST and delimitation. History runs from the Upanishads and the Shunga dynasty to Vijayanagara, temple architecture, the Sylhet referendum and the SNDP Yogam. Geography asks about the atmosphere, earthquakes and tsunamis, Ramsar sites, mangroves and World Heritage sites. Science stays at school level but expects reasoning: a lens problem, a magnetic field direction, molarity versus molality, what cooking soda is, how enzymes act. This page holds GK24's topic-wise GK notes for CDS, written as short facts and tables so that 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 stayed with you.
