Interdisciplinary studies hold significant relevance for candidates preparing for the UPSC exam. Understanding various fields such as sociology, political science, and economics helps aspirants synthesize knowledge across subjects. This kind of approach allows for a holistic view of complex issues, essential for answer writing in the exam. For instance, linking environmental issues to social and economic aspects can provide a comprehensive perspective on topics in the syllabus. This adaptability not only enhances critical thinking but also prepares candidates for essay writing and interview scenarios, where nuanced understanding is crucial.
