My wife recently graduated from a top med school. Her experience was that it was probably 80% "meritocratic" (long hours, grinding it out, being there when someone needs help) and 20% "political" (knowing the right people in the department, knowing what research projects will be good to join and what projects are dogs). To be the top student, you need to know the material well and be productive at research and be a good service provider (good manners, thoughtful, empathetic, etc). The good news is that departments generally give very good opportunities and mentorship to anyone student who shows an aptitude for grinding. Basically, to be in the top 1/5 of the class is all about getting in your reps, and the things that separate the members of the top 1/5 of the class is who they know, who knows them, and the impact and scope of the projects and procedures they were trusted with.
