Evaluation techniques to assess the effectiveness of study methods for UPSC include self-assessments, peer reviews, and mock tests. Self-reflection allows candidates to identify strengths and weaknesses in their understanding of subjects. Peer reviews provide external feedback, which can highlight areas for improvement. Additionally, undertaking regular mock tests helps simulate exam conditions and allows candidates to track their progress. Analyzing results from these assessments can guide aspirants in adjusting their study strategies, recognizing topics that require more attention, and enhancing overall preparedness for the examination.
