CCRN, SAE, Barron's, AACN

[emjwakefield]

I am studying for the CCRN currently and have logged almost 100 hours of dedicated studying. I did the AACN CCRN powerpoints and voice-overs & took notes, read through and made notecards of the most important points in the Barron's book (using the CCRN blueprint). Then, I spent many hours reviewing the notecards. I took one of the 150Q tests in the Barron's book and did poorly (62%). I then paid for and took the SAE (from AACN) and did well (82%). Does anyone have input on which tests are more indicative of how one will do on the CCRN? How about input on if the questions on the CCRN are more like the Barron's book or the SAE? I have also bought the 150Q Practice CCRN Exam Questions Adult (paperback) book and intend to do that soon. Any feedback is appreciated.
