Interdisciplinary subjects like public administration, sociology, and economics can enrich general studies preparation for UPSC. These subjects provide a multifaceted understanding of societal structures, governance, and economic principles. Integrating topics reinforces learning and aids in constructing a holistic view, essential for both prelims and mains. For example, linking political theory with real-world applications in governance enhances comprehension. Additionally, examining environmental studies alongside current affairs prepares candidates for interdisciplinary questions. This approach encourages critical thinking and improves overall preparation efficacy.
