Aspirants can leverage comparative analysis in preparing for examination case studies by evaluating policies, programs, or issues across different contexts. This method helps in identifying similarities and differences in approaches, outcomes, and effectiveness. Such assessments can lead to a deeper understanding of the implications of various solutions and the socio-economic factors at play. Furthermore, comparative analysis enhances critical thinking and allows candidates to construct well-reasoned arguments, which is essential for both the written exam and the interview stage of UPSC preparation.
