Calculating NBME pdf?

[Streptokinase]

So I've come along the pdf versions of the NBME exams. I've searched the forums and from the limited info that I've found, you can calculate your three digit score by multiplying your percent correct by 1.45?

Anyone have an idea if this is correct or not? Thanks 👍

Well, considering that would give you a maximum possible score of 145, somehow, I don't think that's accurate. 😛 If you're talking about the CBSE which has 200 questions, maybe you mean multiply your raw score by 1.45? That seems like it'd underestimate your score pretty substantially (64% to pass?!), but I guess it's at least sort of close-ish.

here's a chart

Milkman: too funny

Kryptik: thanks for the chart...it's legit?

To me it seems like it underestimates your score. I would think getting 90% of the questions correct would give you a higher score than 245, which wouldn't even put you in the top 10% of test takers.

Getting 90% on the NBME gives you a 250 which is in the low 90th percentile on that chart and also seems to be even by USMLE. that's around 1.5 std deviation which is just about 90 %ile b/c 1.645 std dev above is 95% and 2 is 97.5%. Getting 90% questions correct on the real thing would prob still give you a higher score than 250( i would think)but thats because of sample test questions and other factors though, that kind of stuff is taken out of the equation i think when the estimates are made.

Loads of the answers on the pirated copies are just plain wrong.

Watch out...

This is worth a second mention. The NBME exams floating around can be useful but some of the answers are incorrect... a few were so blatantly wrong that I almost started to question myself. The amount of $ "saved" is not worth that much confusion. Pay for the real version online and get a proper score so you know where you're at. Otherwise you're taking a gamble.

...and a third mention. The feedback on your weak areas are invaluable.

Looking at that chart it seems reasonable. I think i remember reading on here though that the NBME's seem to be more harshly curved than Step 1. Maybe its just its the day after the test and im freaking out cause no one has a clue how this thing is scored.

That is the reason I am not using PDF's of the NBME's. I'm up to my neck in loans anyways, so forking out some more cash for the NBME's and an accurate predictor of my score isn't too rough. To me, at least.

the conversion on that pdf doesnt match up with my NBME score and my predicted 3 digit score provided on the test itself (mine said 450 ~ 213)
