I know Dr. Cuccurullo(sp) from my JFK rotation. I was allowed to see some of the rough draft chapters of the book and found it to be concise but suprisingly thorough. Considering the fact that most JFK residents score VERY well on the boards 80-90th percentile using Cuccurullo's book and teachings 🙂 , I would think many would benefit from the book. I know there were bootleg versions out there even before the publication of the book. That's also a good sign.
