Good for you! Studying for the CCRN took me 6 months of fairly intense review. I used the Core Curriculum, Hazinski's reference on Pediatric Critical Care and the audio CD's, which were fantastic. If you are an audio learner, the CD's are great. I would listen to lectures while driving the kids around and going to work.
If you are committed, you don't need to attend a review course. It just takes time. Interestingly enough, the areas I thought I would hit out of the park (respiratory) were the hardest and the things I really had to study (cardiac, heme/onc) I did well on.
Overall, I have rarely been prouder of myself than when I saw my passing score on the exam. I felt validated and more confident in my abilities to care for my patients. That is worth any amount time and money to me.
Good Luck and happy studying!
