Aspirants should integrate interdisciplinary approaches to achieve comprehensive UPSC preparation. This involves merging insights from political science, economics, sociology, and history to foster a holistic understanding of public administration and policy-making. Interdisciplinary study allows candidates to connect theoretical frameworks with practical applications, thus enhancing critical thinking. For instance, using economic principles to analyze social policies encourages deeper insights. Furthermore, diverse knowledge helps in developing analytical skills essential for the essay and interview segments. Therefore, an interdisciplinary approach significantly enriches an aspirant's preparedness.
