Peer evaluation in improving answer writing for UPSC is highly significant. It promotes collaborative learning, allowing candidates to receive constructive feedback on their responses. Engaging with peers fosters a supportive environment, where individuals can share different perspectives, enhancing their understanding of topics. By critiquing each other's work, candidates can identify strengths and weaknesses in their writing styles and content. This process not only improves individual performance but also nurtures skills like critical thinking and self-reflection. Ultimately, peer evaluation helps candidates refine their answers to align with UPSC standards and boosts their confidence for the examination.
