CPP exam domains — which ones are actually harder than the weighting suggests?

I've been working in permitting for about 6 years, mostly land use and commercial building permits, and I'm planning to sit for the CPP exam in about 12 weeks. I've read through the candidate handbook and the domain breakdown, but I want to know from people who've actually taken it which areas were harder than the percentage weighting suggested.

My instinct is that the regulatory compliance and zoning interpretation questions will be trickiest for me since I'm most used to applying local code rather than thinking abstractly about how different jurisdictions handle similar issues. I worked through a CPP practice test last week and the multi-jurisdictional scenario questions tripped me up the most — they're testing general principles that cut across jurisdictions, which is a different muscle than my day job.

I'm spending about 1 hour a day right now, which I plan to ramp to 1.5-2 hours in the last 4 weeks. The ICC and APA reference materials seem to be the most cited study resources but they're dense. Anyone found a way to move through those efficiently without just reading cover to cover?

Also curious about the format — I've seen mention of 100 questions and a 2-hour window. Is that still accurate? And are there question styles that people consistently underestimate going in?
