Surveys and reports serve as essential tools in enhancing knowledge for UPSC preparation. They provide aspirants with data and insights into societal issues, economic trends, and governance challenges. By analyzing various surveys, candidates can develop a better understanding of public sentiments and key issues affecting different demographics. Reports from credible sources also present relevant statistics and case studies that can aid in formulating arguments during both the written exam and interviews. Additionally, staying informed through these means helps candidates to critically engage with current events, which is crucial for both the Personal Interview and General Studies paper.
