Laura Gasparis videos and her online practice exams together with the Pocket prep for CCRN App, the $12 150-question booklet from aacn. Two days before the exam, I did the self assessment test from acnn/psi. Studied for less than 10 days. Took it last April 13, 2017 and I passed! Got 104. The result said you have to get 87 to pass the exam. Gasparis videos are awesome!!! Highly recommend her online lecture video that comes with practice exams (got it from ccrnreview.com). Questions from her online and the pocket prep app are similar to the exam. And I got two questions from the booklet that appeared on the actual test.
