offline NBME score conversion - timmalik

Hi everyone, can anyone advice how you calculate the offline NBME score into three digit?
Thanks in advance

multiply what you scored by 1.4 e.g 160/200..........>160x1.4=224

Why do you multiply it by 1.4?
Thanks

the total questions on step 1 are 336(48Q *7 blocks), if you divide it by 200(total number of q per form), the number comes to 1.68.

4 blocks of 50 qns each are present in NBMEs.

yes, you are right.but my question is that why you multiply it by 1.4?why not 1.68 ?

[ArchivalUser]

I don't have any idea but I have been using it that way.It is good to use score estimators such as this :

Thanks for the link, for simplicity

total q ,step 1 =336
total nbme q per block=200
336/200=1.68

if you multiply 200 with 1.4 it comes 280.

I appreciate your help.
