Many new schools are not operating care hospitals or systems that provide standardized rotations and therefore standardized experiences of grading that are under the school's control. Obtaining a rotation at a place that has these abilities can get you a leg up. Without this, you will likely be lost in the sea of 1,000 applications as we have no idea about how good you are or are not.
If you find yourself paying tuition to a school that suggests you go out into the world and find your rotations on your own, and the suggested rotations are "shadowing" non-professors who just let you watch them practice, be wary. That isn't adequate undergraduate medical education. Graduate medical education institutions are not fooled by this.
Does you school have Ph.D. programs that contribute to your MS-1 and MS-2 education? Is your school attached to a university, or is it stand alone and for profit? These are not trivial questions and medical education is inching towards the law school model. We are producing lots of lawyers and we are producing a few real lawyers. Medicine is going in this direction unfortunately.
Unlike lawyers, we don't have one test that allows us to practice (the Bar exam). You have to get into a residency and this is the last hurdle that is keeping us honest and credible. We may never shore up the infiltration of the "fake/for profit medical school" industry that is expanding quickly. This will close in when graduates from such schools stop matching. That will be when the water runs over the last dam and large loans will burden MDs with no ability to practice. I hope that will play out somewhere else and not in psychiatry.
