These books are brand new and are the best way to study for this pain in ass test!! I used this same version and score 98%, landing me 20 interviews for orthopaedics!!! there are 3 very comprehensive volumes of info on ALL classes from biochem to pathophys. the huge q book of questions will numb your mind with the most realistic questions to date. Start early- no cramming for this exam!! best of luck either way. Again these books are pristine and I will include a CD with full length exams and detailed analysis of your results. email me for details. ----------k.c.
