i saw this 2008 First Aid Q&A for step 2 ck....they have 1000 questions for step 2 ck....i was wondering if anybody knows how good is this book? they have 8 test format at the end of the book....being an 'offline' qbank, it's impossible to give you a score but maybe based on the procentage somebody knows a score aproximation.....what's the procentage of good answers in order to have a passing score or 90's score on real exam? i know this is hard to predict and some of you might say: get an NBME or Uworld SA.....before that i wanna do as many questions as posible and i'm thinking of trying this book(my UWorld account expire and i didn't extented cause i did all the questions at least 2 times; my exam is in less than 3 weeks)....thanks to anybody who can help.....
