Peer-based learning promotes knowledge exchange and enhances medical education. In surgical training, student organizations help fill gaps in undergraduate education by integrating theory and practice. The "Surgery and Emergency Immersion Month" (MICE), organized by a student organization, offered 40 hours of theoretical and practical classes with specialists and trained students. The event had strong participation and received positive feedback, highlighting the importance of practical learning. This experience reinforces the impact of peer-based learning in preparing better-trained doctors, encouraging similar initiatives in surgical education.
