Mock tests are immensely important in preparing for the UPSC exams as they simulate the actual examination environment. They help aspirants assess their knowledge, time management, and exam readiness. Regular mock tests identify strengths and areas needing improvement, enhancing confidence. The feedback provided post-test allows for targeted revision and deeper understanding of subjects. Integrating mock tests into preparation contributes significantly to better performance in both the prelims and mains, as it fosters a habit of structured thinking and answer writing.
