NBME form 7 distribution - share your score?

[user5454]

Is there anyone who has taken the NBME form 7 who wouldn't mind sharing 1) how many questions you got wrong and 2) what your assessment (CBSSA, the one that goes up to 800) score was?

I'm curious about the distribution in terms of mean and standard deviation of number of questions people answered correctly. It's easy to back-calculate, but I need the above information from at least two people, and I don't feel like paying $120 to take the test twice myself. Thanks!

I think when I took this I got about 26 wrong. (so about 87%). It was a 235 or 237. The NBME curves are rough.

1) 16 incorrect
2) 630

Thank you both!

If you're curious, using my score and johndoe334's, the mean and standard deviation come to about 163.2 and 16 correct questions out of 200 respectively, which checks out pretty well using the numbers from mdeast (translating his USMLE score into a CBSSA score of 580). Given that they set the mean to be 500 and each stddev is worth 100 points, you can use those to calculate your CBSSA score for any number of questions that you answer correctly using the formula: mean + (CBSSA-500)/100*stddev = # correct.

7 incorrect
690 three digit score

So is it totally a linear relationship? No question is weighted differently? With 7 incorrect / three digit 690 that means that a lot of three digit scores are not possible because it goes all the way up to 800.

Yep. That's what they seem to say in their explanation of the scores, and all the scores I've seen so far fit the pattern very nicely.

**Edit** Of course, it's theoretically possible to get over an 800 CBSSA score, in the same way that you can technically get over a 300 on the USMLE step 1... you just need everyone else to do badly with a really low standard deviation.
