Case studies play a crucial role in answering societal and economic questions in UPSC exams by providing concrete examples that illustrate theoretical concepts. They offer practical insights into how policies impact communities and the effectiveness of various interventions. Utilizing case studies helps candidates apply their knowledge contextually, making arguments more compelling and relatable. This approach not only enhances critical thinking but also prepares aspirants for potential questions on policy evaluations, allowing them to demonstrate a nuanced understanding of real-world challenges and solutions within their answers.
