I just graduated this week with my MSN for acute care clinical nurse specialist. I will be sitting for my boards through the AACN (adult critical care CNS). Does anyone have any recommendations for study guides, books, on line classes, etc. I want to be as prepared as possible. Also, do any recent graduates who have taken the AACN exam have any words of advice? And has anyone used the Mometrix study guide? I've never heard of it. Thanks!
