Failed CPSGT twice — what finally worked for my third attempt?

So I've been trying to pass the CPSGT for almost a year now and honestly I was starting to feel like I'd never get there. First attempt I scored a 68, second time a 71 — so close but still not clearing that passing threshold. I work as a sleep tech at a small clinic and my supervisor kind of just threw me into the role without much formal training, which I think is part of why I kept hitting these gaps in my knowledge.

What finally turned things around for me was actually committing to a structured CPSGT study guide instead of just rereading my AAST materials randomly. I also started doing a CPSGT practice test every Sunday morning for six weeks straight — timing myself, reviewing every wrong answer, writing down WHY I got it wrong. Game changer. The polysomnography scoring section and equipment troubleshooting questions were killing me before.

Third attempt I passed with an 82. If anyone else is stuck in that 68-74 range, I really want to help. What's everyone finding hardest about this exam?

This thread is so reassuring, thank you. I sit for mine in three weeks and I've been spiraling. Going to block off Sunday mornings for timed practice tests starting this weekend. The reminder that multiple attempts is normal and not a character flaw is exactly what I needed today.

Congrats on passing! I just registered for my first attempt next month and the equipment troubleshooting section scares me too. Can I ask how many practice tests you went through total? I've been doing maybe one or two a week but I'm second-guessing whether that's enough. Also did you find the actual exam matched the difficulty of the practice questions you were using?

The scoring section is brutal — I passed on my second try but almost failed because of AASM rule changes I hadn't kept up with. One exam tip that helped me: don't just memorize the scoring rules, understand the logic behind them. Like WHY a 3% vs 4% desaturation rule matters clinically. Once I stopped rote memorizing and started thinking it through, the tricky questions got way easier. Also sleep stage misidentification was my personal nemesis until I drilled waveforms daily.
