UPSC GK Questions 2026

Static general knowledge is the larger part of every UPSC general studies paper. The notices name the same areas again and again: the history of India and the national movement, Indian and world geography, polity and the Constitution, the economy and social development, and general science with environment and ecology. The balance shifts from exam to exam. NDA puts about half of its General Knowledge part on Physics, Chemistry and General Science. CSE favours polity, modern history, environment and the economy. CAPF adds security and human rights, and CDS spreads its questions across polity, history, geography, the economy and school science.

GK24's GK notes are written topic by topic in English and Hindi, as short, fact-first chapters that are easy to revise. They cover Indian Polity, Indian History, Geography, Indian Economy, General Science, Environment and Ecology, Art and Culture, Computer, and the fact lists of awards, sports, books and days. A new chapter is added in each subject as the series grows. Each note carries practice questions, and those that have appeared in an exam say which exam and year. Start with Polity and modern history, then Geography, the Economy and Science. Read a note, take its topic quiz, and come back to it in your monthly revision.
