The UPSC exam is structured with specific time allocations for each paper, ensuring candidates can manage their time effectively. Generally, there are three stages: the preliminary (objective), main (written), and interview phases. In the preliminary stage, candidates face two papers, each lasting two hours, focusing on general studies and aptitude. The mains consist of nine papers, with essay-type questions that typically allow three hours for each paper. Time management is critical throughout the process, as candidates must balance understanding the syllabus, practicing answers, and adhering to time limits during the actual exam.
