Interdisciplinary studies are pivotal for comprehensive UPSC preparation as they foster a holistic understanding of various subjects. The UPSC exam tests a candidate's grasp of diverse topics, requiring knowledge that spans politics, economics, environmental science, and ethics. By integrating knowledge from multiple disciplines, candidates can develop critical analytical skills and enhance their ability to tackle complex questions. This broad-based approach also helps in improving overall personality development, which is crucial during the interview stage. Thus, interdisciplinary studies not only enhance subject comprehension but also prepare candidates for various aspects of the UPSC exam process.
