Current affairs are crucial for preparing for the UPSC exam as they contribute significantly to the General Studies papers and the interview stage. A thorough understanding of current events helps candidates in topics like polity, economy, and international relations. It also aids in developing a well-rounded perspective necessary for the civil services. Candidates are expected to analyze, critically evaluate, and correlate current issues with fundamental concepts in Indian and global contexts, making current affairs integral to success in the overall examination process.
