The weightage of different subjects in the UPSC Civil Services examination varies, influencing an aspirant's preparation strategy. In the Prelims, the General Studies paper constitutes a significant portion, covering topics like Indian History, Geography, Polity, and Economics. The Mains exam has a deeper focus, with two General Studies papers, an Essay paper, and optional subjects contributing heavily to the overall score. Candidates must prioritize subjects based on weightage and their strengths. Regularly reviewing the syllabus and previous years' papers helps in identifying trends and focusing efforts on high-weightage topics.
