I plan to take the FNP certification exam in May 2011. I am wondering where is the best place to find used, but recent, certification review material? I have searched Google, craigslist, eBay without much luck. I am particularly interested in Fitzgerald or Barkley series that includes audio CDs (I could not believe the price they are asking for these!) Also looking for review books that focuses mainly on questions. I figure many students get these review materials and then they turn into paperweights after passing the exam. If anybody has any good suggestions or possibly knows of sites or blogs were these may be easier to get, I would love your input. Thank you for any help or suggestions
