Subjects with a high success rate among UPSC candidates often include Public Administration, Geography, and Political Science. These subjects are favored due to their vast availability of resources and high overlap with the General Studies syllabus. Public Administration provides practical insights into administrative processes, while Geography offers a strong foundation in both physical and human aspects crucial for various exam formats. Similarly, Political Science cultivates analytical skills and critical thinking, connecting theory to current affairs, making it relevant to both preliminary and mains. Therefore, choosing well-resourced subjects can enhance the likelihood of success in the competitive exam.
