2 questions: 1. has anyone tried taking a "test run" of step 1? i know the prometric center offers this for $40. if you've only heard about someone doing this second hand....what was their take on it? 2. i keep hearing that the "flavor" of the test is different than what can bee found on qbank and BSS. i think what i hear most is that the physio questions involve experimental situations with a lot of stuff some of us have never heard of. while i'm confident that i'll be able to make sense of these sorts a questions i'd like to find questions that simulate a little better. it seems like qbank rarely goes beyond pressure/volume curves (or something as easy to decipher). BSS gets a little trickier but nothing like what i hear from friends who have taken the beast.
