Self-assessment contributes significantly to refining preparation strategies for UPSC by enabling candidates to identify their learning gaps and strengths. This process involves reviewing performance in mock tests, analyzing study habits, and reflecting on retention rates. By understanding areas requiring improvement, aspirants can modify their study plans accordingly, focusing on weak subjects or enhancing time management skills. Regular self-assessment also fosters accountability, motivating candidates to stay committed to their goals. Consequently, a systematic self-evaluation helps optimize preparation strategies, ultimately leading to improved exam performance.
