Self-reflection plays a crucial role in enhancing a candidate's preparation strategy for UPSC by allowing them to assess their strengths and areas needing improvement. Regular self-assessment encourages candidates to adapt their study methods and focus on weak points. Engaging in reflection can illuminate gaps in knowledge, build a deeper understanding of subject matter, and sharpen critical thinking skills. Additionally, considering feedback from mock interviews and tests can guide candidates in refining their approach, ultimately leading to a more tailored and effective study plan that aligns with UPSC requirements.
