If you want this kind of success story, search for username: Luckiestone.
In my opinion, he goes down as the "luckiest" person in the history of SDN. I was amazed that the username held true.
If you figure there's a bell curve of results, where most people score where they had on their NBMEs, and some people are above and below, this guy beasted the real deal.
His NBMEs and UWorld% were hugely under-predictive, although note that his UWSAs are highly accurate.
Search for his story on the 2012 scores thread. His post is on page 57 of that thread.
