Hey! Not sure if you still need info or not but I just took AACN AGACNP certification and passed today. Good grief-- it is SO much easier than these review course people make it out to be. I TOTALLY think that the review course developers and review book writers create hype just to sell their products-- I really do. It is a very straightforward exam. Know physical exam basics, EKG patterns for MI's, acid-base disturbances, major endocrine issues, and electrolyte abnormalities.
