Hi. I took the ANCC exam about 3 weeks ago, and I understand how you feel. I used Barkley's review CD's and study manual, and it was a huge help. That was actually ALL I studied, but I spent about 5 weeks going over it and over it... I passed the exam, and found that what I got from the review was really good. I have heard that Fitzgerald's is really good too. Spend time studying, but give yourself time to breathe, too. Good luck!
