Weird... Someone here posted a 237 with a 2 digit score of 96

And also, my score report says the mean is 216 and the sd was 21 which is a little different from what other people's, and a friend of mine has a 218 and 24. I think different versions of the test have slightly different means and SD, and depends on which questions you get

really weird, isn't it?

And the range of scores on my score report says 144-288, and that friend of mine got 279, so yes, there are indeed people out there who get those obscene scores...

I read in another post that someone did the stat analysis with Z tables and figured out the percentiles. Thanks for the pure stats info... According to a dean at another medical school who just had a meeting discussing their school's step 1 performance, he said that the curve of the Step one in recent-years is bottom-skewed, meaning there are more people getting below the mean than people getting above, so the percentiles of those with higher scores should be up-shifted and people with below the mean scores should be down-shifted. So keep that in mind.

And according to the dean of students at my school, she said that the 2 digit score is probably a more down-to earth way of judging how you did on the exam, while the 3 digit score is more percise statistical measurement. According to her, the 2 digit score is supposed to mean: suppose you take a random sample, of say, 100 students of MS2's in the US and Canada who are 1st time takers, and set the scale on a 75 pass (a more-or-less common standard among medical schools) and a 85 mean (which is very typical of medical student performance on their class exams across the nation), your 2 digit score means the score you would get under this condition, +/- 2 points. On this scale, you will notice that the 3 digit scores of 246 or so or above will all get 99's - this just means that in a classroom setting the testing the difference between, say, a 250 and a 280, although is statistically significant (according to the 3 digit score that's 1.5 or so sd) is insignificant. However, there are a world of difference between say a 200 and a 230, the same 30 points on the 3 digit score, will amount to a huge 10+ point difference on the 2 digit score.

As you can tell I am kind of bored, but just for those people who are interested...
