It is worth doing the Prometric Practice USMLE for 45 bucks. I took it, consciously choosing not to do the released items so I could not prepare. 2 days after COMLEX, I took it and found it fair, on the same level as Q bank but easier than COMLEX. I left with a score of 109/150. When I got home and saw what I missed I was pissed. But I bet that happens with any exam for some of us. If only I had one more day to study behavioral!!!!!! Something just has to give. But for you guys planning on scoring in the 80's for the real USMLE, you probably ought to call ahead to see that they have a leather receliner for his Majesty!! People don't generally break the 80% mark on USMLE. An 80 generates a 3 digit score of some unhuman score of 280. My buddy did the practice test last year (which is why I did it), and he scored a 72% on the practice exam. His real exam'3 3 digit correlation was almost on the head at 248. The 72% predicted he would have scored a 252. Not too bad a target practice...taking the same type of test next to the loud typing GRE'ers, under the same pressure( sort of). My main focus was to see if it correlated with Q Bank and to see if it correlated with my real score, and to make sure I wasn't in the 50% on the practice questions. My guess is everyone who is honest with themselves will agree a correlation exists. I'll start off the thread.

Qbank-74%
practice items at Prometric (NOT at HOMe second go round!! - 72%)
Predictions based on these observations is 246. I will post in a few weeks when I get my score and then lets let science crunch the numbers.
