Time management differs significantly between the preliminary and Mains stages of the UPSC exam, primarily due to the varying formats and demands of each phase. In the preliminary stage, candidates must focus on quick decision-making to answer multiple-choice questions within a set time limit, requiring swift recall of information. Conversely, the Mains necessitate in-depth written responses that require thorough understanding and analysis, often leading to longer preparation and writing times. Candidates must tailor their strategies to optimize performance across both stages effectively.
