Static general knowledge makes up about 90% of Part B of the NDA General Ability Test, about 360 of its 400 marks. The NDA & NA (II) 2026 notice divides it into five sections: Physics (about 25%), Chemistry (about 15%), General Science (about 10%), History, Freedom Movement etc. (about 20%) and Geography (about 20%). Half of Part B is science. Physics covers matter, motion, gravitation, heat, sound, light, magnetism, electricity and the working of everyday devices such as the siphon, pressure cooker, periscope and safety fuse. Chemistry covers changes of matter, elements and compounds, common gases, acids, bases and salts, carbon, fertilizers and the materials used to make soap, glass, cement and gunpowder. General Science covers cells, the human body, diseases, diet, the solar system and eminent scientists. Section D spans Indian history and culture, the freedom movement, the Constitution, Five Year Plans, Panchayati Raj and world history from the Renaissance to the Russian Revolution. Geography covers the Earth, rocks, oceans, the atmosphere and climate, and India's resources, industries, ports and trade. This page holds GK24's topic-wise GK notes for NDA, in English and Hindi, written as short facts and tables. Read a topic, then solve its quiz and previous-year questions on this site.
