i have it (got it free cuz i work there) and its pretty good but way harder than any other physio questins.....i do well on them only b/c i take them with my classess since we are systems based......i dont thk i'll be using it for boards though but i think if you need extra practice that may be the way to go....i loved the GI questions, didnt care much for the renal questions, resp were really hard, cardio wasnt bad.....thats all i can remember! but if youre bad at GI physio i thinkt he bank is great 🙂 haha sorry i know that prob wasnt much help!
