Peer feedback is significant in refining essays and answers for the UPSC examination as it fosters diverse perspectives, enhances critical thinking, and identifies areas of improvement. Receiving constructive criticism from peers allows candidates to understand their weaknesses and improve their writing and argumentation skills. This process not only strengthens their ability to articulate ideas clearly but also instills confidence in presenting their thoughts in a structured manner. Engaging with multiple reviewers can lead to a more polished and comprehensive final product, which is essential for succeeding in a competitive exam like UPSC.
