Peer reviews of essays can significantly improve writing quality for candidates preparing for the UPSC exam. By receiving feedback from fellow aspirants or mentors, candidates can identify strengths and weaknesses in their arguments, structure, and style. Constructive criticism encourages revisions that enhance clarity and coherence, aligning essays more closely with the exam format. Peer assessments also promote accountability and motivation, fostering an environment of collaborative learning. Furthermore, engaging with others' work offers fresh perspectives, broadening candidates' insights and helping them articulate ideas more effectively. Thus, peer review is a valuable tool in refining essay-writing skills.
