General Knowledge preparation for IB ACIO should be divided into static GK and current affairs. For static GK, refer to Lucent’s General Knowledge, Manorama Yearbook, and the India Yearbook. Focus on topics like Indian Polity, History, Geography, Economics, and Science. Create short notes or flashcards to revise facts regularly. Use online GK quizzes and apps to test your knowledge and improve accuracy. Static GK does not change, so mastering it can give a significant advantage. Combine this with a strong grip on current affairs for a well-rounded GK section performance.
