First of all, ignore FlatEarth22. He's a semi-troll. It's unbelievable to me that students don't realize that certain schools like Baylor, Northwestern, Vandy, etc have board scores close to 240 because they teach to the boards. Yes, they have intelligent student bodies, but they also have curriculum's which foster a better learning environment for boards. Wash U, for instance, does not teach to the boards and only gives students 4 weeks. Whereas, Vandy gives 7 weeks, UVA 9 weeks, and USC (keck) 10 weeks. I'm non-traditional and have two high school buddies who were part of the 2011 vandy graduating class. One got a 33 MCAT and the other a 34, and both got greater than 260. They harped on Vandy's amazing approach. Whereas, my buddy, who is a 4th year at Wash U, only got a 239 despite earning a 39 on the MCAT. The Wash U student is MUCH more intelligent than the aforementioned two.
Now, you'll say this is anecdotal and it is, but to only attribute high board scores to smart students is equally erroneous as not considering the school's didactics. Finally, look up the poster Jalby who has repeatedly argued that USC is a school that consistently produces some of the highest step one averages even though it is barely a top 40 school. Now, why could that be? maybe because SC teaches to the boards and not mindless detail and gives students 10 weeks to study. So, where you go to medical school has the potential to influence your score.
In closing, let's take NU and Chicago. UC is the higher ranked school and has the better match list and much fewer students. However, their board scores are mediocre. Whereas, NU, which teaches to the boards hovers around 240, with twice as many students! How could this be? Aren't they equally talented? Well, one school is traditional and doesn't teach to the boards whereas the other is systems based and has exams and assignments modeled after the board. So, students should consider the curriculum.
Now, I agree that the biggest control is the talent of the student. However, I know for a fact that I wouldn't learn as well at a school like UChicago or Wash U compared to a systems based school. So, one should consider environment, cost, didactics, just like any other consideration. Finally, FlatEarth, your post was hilarious because the Vandy student's post was comparing it to upper-echelon schools, and not mediocre state school. As an aside, Harvard doesn't usually leave the country in board scores? Why? They attract top-notch students. They don't teach to the boards. Study time for the boards and didactics helps because it determines whether you have to spend your time memorizing worthless detail or learning the key concepts and how to integrate like you will have to do on test day. Don't be so quick to blow something off without first giving it some consideration. My long 2 cents.
