Case studies from around the world significantly enrich candidates’ answers in the UPSC by providing real-life examples that illustrate theoretical concepts. Such case studies can demonstrate successful governance models, social issues, or economic policies, allowing candidates to draw parallels with India's situation. Including global contexts encourages a broader perspective on local issues, showing evaluators that candidates are well-versed in international affairs. This enhances the quality of answers and exemplifies a comprehensive understanding that is pivotal for the UPSC interview process.
