Earlier this evening I purchased and completed the online self-assessment practice exam that is available on the HPNA website and is made up of questions from previous exams. Without preparing or studying, I got an 86% overall. Because of this, I feel more confident about passing the certification exam so I signed up to take it on June 7. I ordered a study book off of Amazon and plan to study before the exam, of course, but since I did so well on the self-assessment and it is made up of exam questions, between that and the study book, do those of you who are certified think that I should be able to pass? My employer will reimburse me for most of the $395 (!!!!) cost to take the exam...if I PASS. Now I'm getting a little nervous.
