SSC GK Questions 2026

Static GK decides most of the General Awareness score in SSC exams. The CGL, CHSL and CPO notices describe it in almost the same words: questions on India and its neighbouring countries in History, Culture, Geography, the Economic Scene, General Policy and Scientific Research, and on everyday observation in its scientific aspect. The GD notice adds Sports, General Polity and the Indian Constitution, and the MTS notice lists Social Studies, General Science and Environmental Studies up to the 10th Standard. This page brings together GK24's GK notes and practice questions tagged for all five SSC exams. The notes follow a subject-wise syllabus, one topic per note in English and Hindi: Indian Polity, Indian History, Geography, Indian Economy, General Science, Environment and Ecology, Art and Culture, Computer, Sports, Awards and Honours, Books and Authors, Days and Dates, and Static GK. Each note is written as short facts and tables so that a topic can be revised in one sitting, and each ends with multiple-choice questions and explanations. The level is what changes between exams: read MTS and GD topics at Class 10 depth, CHSL at Class 12 depth, and CGL and CPO at graduate depth, where questions ask for the article number or the year rather than the broad idea. Start with Polity, History and Geography, which fill the most questions in past papers in GK24's reading, then move to the Economy and Science. After each note, solve its questions here and your exam's previous-year questions on its own page.

An astronaut whose weight on the Earth is 600 N experiences weightlessness on International Space Station orbiting around the Earth. It means that

  1. A.acceleration of the astronaut is zero
  2. B.normal reaction of the space-station floor on the astronaut is zero
  3. C.gravitational pull of earth on the astronaut is zero
  4. D.space station applies a centrifugal force on the astronaut
Show answer
Correct answer: B. normal reaction of the space-station floor on the astronaut is zero
