The syllabus for the UPSC Prelims examination consists of two papers: General Studies Paper I and General Studies Paper II (CSAT). Paper I covers a broad range of topics such as current events, history, geography, Indian polity, and general science. Paper II, or CSAT, assesses comprehension, logical reasoning, and numerical aptitude. Each paper is crucial as it tests candidates' understanding of fundamental concepts and their reasoning abilities, setting the foundation for their further preparation in the Mains.
