I'm not ashamed to admit it took me three tries to pass the SGNA certification. The first time I walked in thinking my 8 years of GI nursing experience would carry me through. It did not. I scored a 68 and needed a 75. Second attempt I bought a random study guide off Amazon, read it cover to cover, and still came up four points short. I was ready to give up.
What changed everything was actually using a proper SGNA practice test with timed conditions. I mean actually sitting down, no phone, 150 questions, two hours — simulating the real thing. My weak spots were infection control and reprocessing standards, which I genuinely thought I knew cold because I do them every single day. Turns out doing something and being tested on the regulatory nuances of it are very different skills.
I passed with an 82 on my third attempt. Happy to answer questions about what resources I used and how I structured my last six weeks of studying.
