I was mindboggled by the exam - a lot of the questions surprised me and for me, I got more questions regarding knowing other role's jobs such as sterilization/processing, anesthesia concepts. The CCI flashcards were helpful, and I got this app (CNOR Pocket Prep) that helped me study on my breaks as well. The AORN CNOR Review course was a good extensive review but I never got around to finishing it because I felt like it was dragging too long.
