Contrary to SDN think, people's decisions as to why they choose to matriculate at a particular med school isn't based solely on USWNR rankings or prestige. There are many other factors that can heavily affect that decision: huge differences in cost (with not as huge of a benefit at the more expensive school), close proximity to family (which can be a life saver if you're cramming during exam week and you need your chores to be done), location, etc. which can affect your medical school performance and overall mental health.
Perfect example - there was an SDN user here who was deciding between NYU and a state school (in which her family lived in the city). The cost difference was so huge that it wasn't worth it (yes, the difference in tuition was that huge, esp. as the person had received a scholarship at the state school). So reluctantly the person went to the state school, and w/in the first few months had an emotional crisis (unrelated to the school). Guess what? That person had their family support system in the same city, which would make overcoming that crisis much easier. Would have been much harder if that person was going to school in New York with their family in a completely different state that would require a plane flight.
Making a decision of which medical school to go to and trying to game the system thinking that if you go to the "dumber" medical school, bc you think you'll have a much easier time being at the top of the class, so that you can match into Derm (much less Derm in a huge metropolitan city like SF/NYC/LA) is a very foolish game plan.
@Goro knows every trick in the book premeds have played by now. If it's been thought of before, it's been done, and it has failed.
