I had to look up what the heck a green book rotation even was...That being said, I'll uncertainly say that they are not all green book as there are definitely a great number of rotations that likely have you never stepping foot in a hospital that has a residency in the field you happen to be rotating in during a given month (if you even happen to set foot in a hospital that month) or the hospitals aren't teaching hospitals. I also don't think it really matters, as AZCOM's students don't seem to be struggling to match into residencies or in obtaining licenses. Again, I could definitely be mistaken in my interpretation though since I've just learned of "green book" rotations in the past ten minutes.
