ORYUMI

Most of the CNOR threads here are from 2020 or earlier, so I figured a current one might be useful. Hit my two years and 2,400 hours, applied that same month, passed first attempt about four weeks later. No review course, no textbook, no question bank subscription. Total spend on prep was zero. I read a lot of the older threads here while I was studying, so here's what actually worked in case it helps someone. Caveat up front — I passed once. I can't tell you how much was my method versus two years of standing in the room every day. The thing that made a month feel possible I looked at CCI's content outline before I studied anything. Management of Intraoperative Activities is 34% of the exam. That's the job we already do. So I didn't split my time evenly. Almost nothing on intraop, and most of it on what daily work doesn't teach you — sterilization science, indicator classes, legal and ethical terms, which org owns which guideline. Questions first, reading second I never read to prepare for questions. I used questions to figure out what to read. Went straight into practice questions on day one knowing nothing and got a ton wrong. That's the point — a wrong answer shows you a gap in thirty seconds instead of an hour of reading that might not even cover it. After a few hundred you start seeing which topics keep coming back and how they write a stem. I'm not someone who can read a textbook front to back. But I can get something wrong and want to know why. On using AI for this I used ChatGPT the whole month as a study partner. Not for anything clinical, and not as a source — I cross-checked anything surprising, and it did get me once. My notes had ejection fraction as 55–70% because that's what most physiology references say. CCI's own practice PDF uses 60–70%, citing Berry & Kohn. Same with cardiac output, I had 4–8 L/min and the periop sources use 3–6. If both show up as options that's a point gone. The single most useful thing I did with it: after every topic, ask what are the wrong answers that look right here? Textbooks teach you the correct answer. The exam is built out of the plausible wrong ones. Free stuff I used CCI's own practice questions — free PDF on their site, answers and rationales and a textbook citation for every item. Start here, it's the only thing written by the people who write the exam. Short, so use it to calibrate. Mometrix free practice test. Decent volume, it's a funnel for their paid course but the free tier is usable. Quizlet, just search CNOR. Where most of my volume came from and it works on your phone, which is why I could study between cases. Uploaded by strangers though, so verify anything surprising. A few random things Test at a center, not at home. Not worth trusting your internet and their proctoring software for four hours while you're already nervous. 3 hours 45 is a lot of time. I braced for a crunch that never came. Slow down and read the stem. SPD was heavier than I expected — including wet packs. A pack that's damp after sterilization and cool down is contaminated and gets reprocessed regardless of what the printout says. I never felt ready. It just gradually became true that more questions were landing inside what I knew. Still getting things wrong the week I tested. The signal isn't "I stopped making mistakes," it's "my mistakes got weird." What I'd do differently Nothing about the method. The only time I wasted was the first afternoon, shopping for review courses and books before deciding they were too expensive. One afternoon spent confirming I didn't need to spend anything.
