CPI exam prep — anyone actually passed without formal training?

I've been trying to prep for the CPI on my own for about 10 weeks now and I'm honestly not sure if I'm covering the right material. Most of what I've found online is either too surface-level or requires you to already have completed an accredited course. Did anyone here go the self-study route and actually pull it off?

My background is in product management, so the design thinking and ideation sections feel pretty natural. It's the implementation frameworks and measurement side where I keep second-guessing myself. I've been spending about 2 hours a day on this, maybe 3 on weekends, and I'm still not confident I'd hit 70% on the actual exam.

The practice questions I've found vary wildly in quality. Some feel like they're testing real application of innovation principles, others feel like they were written by someone who's never actually run an innovation program. Has anyone found a bank of questions that actually reflects what's on the real exam?

Planning to sit for it in about 4 weeks. If anyone's been through this recently, any advice on where to focus would be huge.

I passed mine about 6 months ago without any formal coursework. The official body of knowledge document was the single most useful thing — I basically built my entire study plan around it. Spent about 60 hours total over 8 weeks.

The implementation and scaling sections tripped me up too. What helped was mapping each framework to a real project I'd worked on — made it stick way better than just re-reading definitions. I scored a 74% on my first attempt, which was close but I'll take it.

4 weeks is doable if you're already putting in 2-3 hours daily. I'd prioritize the innovation measurement and ROI sections — those had more questions than I expected. Good luck with it.

Product management background is actually solid prep for this. The exam leans more into the strategic and facilitation side than pure methodology. Don't overthink the theory — focus on applying it to scenarios.
