Candidates can adopt an interdisciplinary approach by integrating insights from varied fields like history, political science, economics, and geography in their UPSC preparation. This broadens their perspective, allowing for a more holistic understanding of issues. By relating concepts to real-world scenarios and current affairs, aspirants can enhance their analytical skills. This approach also aids in essay writing and general studies sections, as diverse knowledge fosters critical thinking and comprehensive answers. Collaborative study, discussions, and interdisciplinary resources can further bolster this preparation strategy, making candidates more versatile and adaptive.
