I am just wondering about the correlation of Kaplan Qbank scores to actual passing on the USMLE Step 1. I know that others have posted their experiences and it seems that Kaplan is more difficult than the Step 1. My average for the past month on Qbank has been 55%. I have been studying for about 1 month. It doesn't go up or down by more than 5% regardless of whether it is a comprehensive test or a subject-specific test. Can anyone comment on whether I have a chance of passing with a 182+ next month when I take the Step 1?
Another question: What exactly does 182 mean? If you take 350 questions total but subtract 50 as experimental, that leaves 300. So 182 divided by 300 would make 60% as passing. However, 182 corresponds to 75 as passing per the language of the Step 1 examiners. I know people who have scores in the upper 90s, but their 3-digit-scores are like 250+. So 250 divided by 300 would only be 83%. Confusing.
Oh well. Best of luck to all.

The passing score of 182 corresponds to a percentage score of 50 to 60%, depending on the level of difficulty of your individual exam. That is per Kaplan. What most of the students at my school say is that if you are getting about 70% on QBank then you will definately pass.

The top score possible is 267. So 267/300 is 89%. So I don't think this is the right way. My understanding of the "shelf" exams given for each subject (biochem, path, etc.) and administered by NBME is that they make the national average 70% (not number correct/total questions), and then from there give the test taker a percentage score based on comparison to the national average.

Hi all,
I'm not sure but this is how i think it goes. The 3 digit score correlates roughly to the number of questions you would have gotten right out of 300 if you had received a normal ( medium difficulty) test, since every test is different the actual number of question you got right is probably multiplied by some kind of difficulty factor calculated based on your personal exam toughness...
This would explain why 180 ( 182 now actually...) out of 300 is required to pass, wich gives you 60%.
Now for the 2 digit score, we know that the passing 2 digit score is 75, wich is 60 + 15. So 180 = 75. We also know that the mean is 215 (3dig) = 85 ( 2dig), wich ones again seems to be 215/300 = 71% add to that the .15 and we get our 2dig score of 85 ( well yes, 86 actually...)
Ok, i'm really bad at expalining this, i know. So your 2 digit score is the percent of questions you would have gotten right on a normal difficulty exam + 15% ! This mean that anyone answering 84% or more questions right on a normal test gets 99! Wich would also explain why some people say that the 3dig score is more important, since you cant differenciate between someone who gets 84% right and someone who gets 94% right based on 2 digit. I very well might be totally WRONG!
ALL THIS LEADS TO MY QUESTION! all you people who got 99, was your 3 digit scored capped at 255? or can you get 99 and ,theoretically, a maximum of 299 ?
Writing it in a month, should be studying not calculating.... oh well, Good luck to all you test-takers !
