CDS Previous Year GK Questions

Previous-year questions are the most reliable guide to the CDS General Knowledge paper, because the syllabus in the notice is one paragraph long and the paper is not. UPSC uploads the question papers of every CDS on upsc.gov.in the day after the exam, so a full record of what was asked exists for each cycle. Reading them shows the weight of each area, the depth UPSC expects in Polity, History, Geography, Economy and Science, and the question forms it prefers: statements with "which of the above are correct", "how many of the following pairs are correctly matched", match the lists, and arrange in chronological order. Many topics return: writs and constitutional bodies, dynasties and reform movements, Ramsar sites and World Heritage sites, budget and balance-of-payments terms, and school science applied to everyday situations. This page collects CDS previous-year General Knowledge questions in English and Hindi, each with the correct answer, an explanation and the topic it belongs to, so that a question leads you to the GK note that covers it. Use them in three passes: untimed to learn, timed to build speed, and a week later to revisit your wrong answers.
