I did three of my core rotations at BronxCare and my honest take is that the patient volume is genuinely insane in a good way for learning. You are seeing real pathology constantly, the ED is busy, the medicine floors are packed, and you are never standing around with nothing to do. The attendings vary a lot though. Some of them are fantastic teachers who will quiz you and push you and write you detailed evaluations. Others are overwhelmed and you can tell they see students as a secondary concern. You have to be proactive about introducing yourself, showing up early, and making yourself useful or you can drift through a rotation there without getting much out of it. The experience is very much what you put into it.
