I have registered to take CNOR exam soon. In my free time, which is minimal, I have tried to review for the exam. I am using CNOR Exam Study & Practice resource and the Nursing Standars 2004 book. I feel overwhelmed, and need to pass this exam. I have been an OR nurse for 15 years. When I take the practice tests, I do not do very good on them. How can I study in a short period of time and be successful in passing this exam? Please help :)
