Teaching others as a study strategy for UPSC has multiple benefits, including reinforcing one's understanding of concepts and enhancing communication skills. When candidates explain material to peers, they clarify their own thoughts, discovering gaps in knowledge that require further study. This method promotes collaboration and builds confidence in public speaking, vital for interviews. Furthermore, teaching fosters a sense of accountability; candidates are more likely to prepare thoroughly when they need to convey information. Ultimately, this strategy can significantly enrich both the teacher's and the learner's understanding of the subjects.
