Peer groups can positively influence UPSC exam preparation by offering a platform for collaboration, motivation, and mutual support. In a peer group, aspirants can share resources, exchange knowledge, and engage in discussions, enhancing their understanding of complex topics. This collaborative environment fosters accountability and encourages consistent study habits. Additionally, peers can provide feedback on answer writing and conduct mock interviews, which are invaluable preparation methods. Overall, supportive peer groups contribute to enduring perseverance, reducing isolation, and creating a balanced approach to intensive preparation.
