Are you sure? I think people might be better off not checking SDN if they have good stats. SDNers sure take a whole lot of pride in not being a Cookie-Cutter applicant. But at the end of the day, if you could have gotten into a US medical without selling your better years to the process, then wouldn't that be better?
I'm currently an MS-1, and I think I'm representative of the general crowd of medical students. I work very hard and spend just about all of my time studying. There isn't much time for fun and games. You have no idea what I would give to enjoy those pre-medical school days again. But sadly, SDN pushes people to give it all away so they can live their lives according to what they think ADCOMs want to see.
We all believe that those who are not on SDN and those who are unaware of it are a disadvantage. But are they? Maybe we are the crazy ones, not them. I know SDN influenced me greatly, but I'm also happy that I was a non-traditional applicant. Otherwise I would have pissed away four perfectly good years of college. 🙁
