I have my CEN in less than a week. I am kind of freaking out. My scores on the ENA CEN Review Book have been 68-72% with all 7 exams. I have been studying for 3 months and thought my scores would improve more. I have watched Jeff Solheims online review, referenced Sheehy's Manual of Emergency Care, and reviewed some of Mark Boswell's youtube videos. I have been an ED nurse for almost 2.5 years. Any advice on what to do less than a week out from CEN? Thanks!
