Interdisciplinary approaches in subjects during UPSC preparation offer several advantages. They encourage aspirants to draw connections between diverse fields such as politics, economics, and environmental science. This holistic understanding enriches their perspective, making it easier to tackle complex problems encountered in the exam. Additionally, interdisciplinary studies foster critical thinking and enhance analytical skills, which are crucial for the mains exam and interview. Employing varied methodologies from different subjects also cultivates creativity in problem-solving, preparing candidates to think out of the box. Ultimately, a multi-faceted approach leads to a more comprehensive grasp of the syllabus, improving overall performance.
