Static General Knowledge makes up the rest of the General Awareness section in RRB NTPC, and the notices name its topics: General Science and Life Science up to Class 10, History of India and the freedom struggle, Physical, Social and Economic Geography of India and the world, Indian Polity and Governance, Indian Economy, Art and Culture, Indian Literature, Monuments and Places, Flora and Fauna, Famous Personalities, the UN and other world organisations, environmental issues, Transport Systems in India, Important Government and Public Sector Organisations, Common Abbreviations, and Basics of Computers and Computer Applications. RRB frames these as short factual questions: the unit of a physical quantity, the year of a battle, the article of the Constitution, the river a city stands on, the full form of an abbreviation, the headquarters of an organisation. GK24's GK notes on this page cover each topic in English and Hindi, arranged the way the syllabus lists them, with the facts RRB tends to ask placed first. Work through one topic at a time, note the lists (national parks, dances, articles, schedules, awards), and pair each topic with its quiz on GK24 to check what has stayed with you.
