Passed CEA first try — the regulations section was harder than I expected

The 40 CFR cross-reference issue you mentioned is real. I drilled the major parts table from the EPA website specifically for that. Anything in the Clean Air Act, Clean Water Act, and RCRA space — know the program name AND the CFR part.

77% first attempt with five years of field experience is solid. The exam feels like it's designed for people with a mix of regulatory and auditing background — pure regulators and pure auditors both have gaps.

The ISO 14001 audit methodology overlap is useful to know. I've been studying and was worried the auditing section would be totally foreign. That helps calibrate my prep time.

Six weeks at 90 min/day is about 63 hours of prep. That tracks with what most people report needing for CEA. Your air quality background probably helped on the regulatory side even if it felt unfamiliar in exam format.

Honestly I almost bailed after my first practice run through the regulations stuff. I kept getting questions wrong on specific RCRA provisions and Clean Air Act applicability thresholds and I remember thinking I've been doing this work for years, why doesn't any of this feel familiar. The issue is the exam tests the federal framework in a really precise way that doesn't care how your state does things or what shortcuts you've picked up on the job. I had to basically relearn regulations I thought I already knew.

But I kept going and I'm glad I did. The thing that finally clicked for me was stopping trying to memorize and just focusing on the logic behind each regulation, like why it exists and what it's trying to prevent. Once I did that the questions made more sense even when the wording was tricky. If you're in that frustrating middle stage where you feel like you should know this stuff but the practice scores aren't showing it, don't quit. It's a weird kind of hard that gets better faster than you expect.

Congrats on passing! I've got five years in air quality too and I'm sitting for mine in August, so this is exactly what I needed to hear. I work full time and have two kids, so studying happened in small chunks — lunch breaks, 20 minutes before bed, weekend mornings before everyone woke up. The climate change stuff caught me off guard when I started, but I found the cea climate change sustainability metrics practice questions really helped me get comfortable with how they frame those topics on the actual exam. Didn't feel like wasted time at all.

The regulations section is what I'm most nervous about. I know the regs I work with daily but the breadth of the CEA is different. Did you do anything specific to study outside your specialty area, or did you just grind practice tests and hope for the best? Asking for a friend (the friend is me).
