Finally passed my AORN periop nursing exam after failing once — here's what helped

I failed my first attempt at the CNOR back in March by just 12 points, which was absolutely gutting after three months of studying. I'd been an OR nurse for six years and honestly thought I knew more than I did. The pharmacology and sterile processing sections completely blindsided me.

Before my second attempt I completely overhauled my approach. I spent about six weeks working through a solid AORN study guide that actually mapped to the exam blueprint, and I started doing timed AORN practice test sets every evening after my kids went to bed — usually 30-40 questions at a time, not just passive reading. That shift made a huge difference in how I retained information under pressure.

Anyone else have experience with the retake process? I'm curious whether others found the second exam noticeably harder or just different. Also happy to share my specific exam tips if people are preparing right now — I had a few strategies around flagging questions that really saved me on time management.

Congrats on passing! The first fail stings but honestly so many CNORs I know needed two attempts. For me the biggest game-changer was doing practice questions in exam conditions — no phone, timer running, no looking things up mid-set. You find out really fast where your weak spots are. I tanked my first two practice tests on counts and documentation, which I thought were my strengths. Ended up scoring 8 points above passing on the real thing.

I'm currently six weeks out from my test date and the sterile processing stuff is killing me too. Can I ask — did you use the official AORN study materials or a third-party prep course? I've heard mixed things about some of the prep courses not being aligned to the current blueprint. Also wondering how many practice questions you did total before you felt ready. I'm sitting around 400 right now and still not feeling confident.

Time management was my biggest issue on the first try. I'd suggest practicing with a hard 75-second-per-question rule even though the real exam gives you more. Trains you to stop second-guessing. You got this.
