I have got 85% correct in the usmle free 150-FRED V2 questions(the sample questions on the usmle.org)
So please any one tell me the correlation with actual exam.
i have seen the correlation on medfriend.org it says 247. how predictive it is?
Any input would be appreciated. taking test in 4 days. i need some confidence for that.
Thank u in advance.

haha you need to take an nbme to find out what your score is. those 150 are very easy compared to the real exam.
although the concepts are the same...what is your nbme score?
