Hi! I have mine scheduled in 2 days.. I am sooo nervous. I have the mometrix PCCN exam secrets study guide that I have been focusing on because it's so straight forward. I also have Pass the PCCN! by Kathleen Farrell (in which I only read the cardiovascular chapter). I've been studying on and off for about a month. I have purchased the AACN practice test and find those really useful, however have used up all my practice questions. Are there any tips you would have for me? Thanks a bunch!
