For aspirants pursuing interdisciplinary studies for the UPSC, the approach should be holistic, integrating knowledge across various fields. Candidates must develop a strong foundational understanding of topics in politics, economics, society, and environment. They should engage with case studies to see real-world applications and enhance analytical skills. Collaborating with peers from different disciplines can also foster diverse perspectives. This interdisciplinary outlook makes candidates more adaptable and better equipped for the exams and subsequent civil services roles, ensuring an in-depth awareness of complex issues.
