The importance of interdisciplinary knowledge in the UPSC exams cannot be overstated. Given the exam's diverse syllabus, candidates must have a grasp of various subjects, including politics, economics, history, and environmental science. This broad knowledge base aids in answering dynamic questions and enhances analytical abilities. Moreover, it assists in connecting different themes and understanding the interrelations among them, which is crucial for both the Mains and Interview stages. Interdisciplinary knowledge not only enriches a candidate's understanding but also boosts confidence and prepares them for the intricacies of public service roles.
