Case studies can enhance understanding of complex governance issues in UPSC by providing real-world examples that illustrate theoretical concepts. They encourage critical analysis and enable aspirants to explore different dimensions of a problem, including historical, economic, and social perspectives. By examining various case studies, candidates can appreciate the complexities of policy-making and administrative challenges. This approach also fosters better retention of knowledge and equips candidates with the skills to address similar issues during the exam. Ultimately, case studies bridge the gap between theory and practice, enriching the learning experience.
