Failed my CPR cert twice — what am I doing wrong here? — Forums

So I'm a nursing student and my clinical rotations start in six weeks, which means I absolutely have to get my CPR certification sorted before then. I've failed the written portion twice now and I'm honestly embarrassed because people tell me it's supposed to be easy. The compression depth and rate stuff keeps tripping me up, and I keep second-guessing myself on the two-rescuer sequences for adults vs. infants.

I've been using a few different resources this week and the CPR Adult CPR practice test has been the most helpful for drilling the specifics. My scores went from like 58% to 74% over three days, so there's improvement, but I need to be consistently above 80% before I feel confident going back in.

Has anyone else struggled with the written portion specifically? I get the hands-on stuff fine in labs — it's the exam tips and memorization around exact protocols that kills me. What finally made it click for you?

The rate and depth stuff tripped me up too. What helped me was a dumb little mnemonic — 100-120 beats per minute, 2-2.4 inches deep, 30:2 ratio. I wrote it on a sticky note and just stared at it every morning for a week. Also the AHA guidelines changed a few years back so make sure whatever study guide you're using is current. Old materials floating around online will actually get you wrong answers on the test.

74% after three days of practice is actually solid progress, don't be too hard on yourself. Give yourself another week of consistent drilling and you'll be there. The written portion really is pattern recognition more than anything — once you've seen the question formats enough times it becomes automatic.

Honestly the two-rescuer vs. one-rescuer differences are where most people get tripped up, you're not alone. The compression-to-breath ratio stays 30:2 for single rescuer adults but switches to 15:2 for two-rescuer pediatric — that's the one that got me. I spent like 10 hours total on CPR practice test questions before my retest and passed with an 88. It's very doable once the sequences stop feeling arbitrary.
