It's hard to believe that you folks could get such good scores without understanding statistics.
Seriously, look at your score sheet. It gives a mean and a standard deviation. You should be able to use that to figure out how well you are compared to the rest of the pool. In terms of asking if a score is "good enough" for a given residency, remember that no score by itself will be enough. You can have a great score, but your LORs and interviews will make a big difference -- more so than for medical school.
Sorry about that. I didn't read all the posts before I responsed. We see so many people with great scores and great insecurities around here looking for validation. Most don't realize that what they are doing makes others feel lousy.
