Peer teaching plays a significant role in preparation for the UPSC exams by enabling candidates to reinforce their learning through explanation and discussion. Teaching peers allows aspirants to clarify concepts and identify knowledge gaps in their understanding. It also fosters a collaborative learning environment, where exchanging resources and insights enhances overall preparation. Engaging with others can build confidence, enhance critical thinking, and improve articulation of thoughts, which benefit both the teacher and learner in mastering complex topics prevalent in the UPSC syllabus.
