Interdisciplinary study plays a crucial role in UPSC preparation as it fosters a more comprehensive understanding of complex topics. By integrating knowledge from politics, economics, history, and geography, aspirants can gain insights into how different domains influence governance and society. This approach encourages critical thinking and equips candidates to draw connections between diverse subjects, making their responses in essays and interviews more nuanced. Furthermore, it enhances adaptability and problem-solving abilities, which are essential for a successful civil service career. Interdisciplinary learning ultimately enriches the depth and breadth of candidates' knowledge.
