Static GK is not a separate section in RRB Group D, but it decides most of the paper's recall marks. General Science is 25 questions of Physics, Chemistry and Life Sciences at 10th standard (CBSE) level as per CEN 09/2025, and the 20 General Awareness questions lean on the standing facts behind the news: the sport, the award, the institution, the state, the river or the scientist an event touches. This page holds GK24's topic-wise GK notes for RRB Group D. The General Science notes go topic by topic through motion and force, work, energy and power, gravitation, heat, light, sound, electricity and magnetism, atomic structure and the periodic table, chemical reactions, acids, bases and salts, metals and non-metals, and carbon compounds, and the Life Sciences notes cover cells, the human body, nutrition, diseases, plants and genetics. The static GK notes cover Indian Railways zones and facts, national symbols, first and largest in India and the world, awards and honours, important days, books and authors, sports GK, art and culture, and the basics of Indian Polity, Geography, History and the Economy. Each note is short facts and tables that can be revised in one sitting. Read a note, then solve its quiz and the previous-year questions on this site to check what stayed.
