UPSC assesses general awareness through a combination of objective and descriptive questions in its examination. Candidates are evaluated on their understanding of current events, national and international affairs, and issues of socio-economic importance. The preliminary exam includes general studies papers designed to test awareness and comprehension levels. The Mains exam further tests this knowledge through specific subjective questions that require critical analysis and application, reflecting the candidates' grasp of various subjects, which ultimately play a crucial role in determining their suitability for civil services.
