Zee, I sat for the CCRN last year in March 2002. It is 200 computerized questions. You can bookmark questions during the exam for review at the end. You have 4 hours to take the exam and will get your results after you finish. It is not as difficult as you would expect. I studied from PASS CCRN by Robin Donohoe Dennison the CDROM review question were very helpful. Review the book then take a practice exam they are retired question from old tests. Do not worry over missed questions. I did poorly on the practices but it focused my study. The current exam included Synergy Model. Review terms for this section it is really common sense to answer these question. I work with someone who recerts every year by taking the exam and she says the questions are not as hard as they used to be. Remember to relax you know more than you think. Hemodynamics are only a small fraction of the exam. I had worked in a ICU only 2 years when I sat for the exam and passed it the first time. :roll
