Passed AEP on first attempt - 6 weeks was enough with the right approach

Just got my official AEP certification letter and wanted to share my study approach since I see a lot of people asking whether 6 weeks is enough time. For me it was, but I was pretty structured about it and I had about 5 years of field environmental work behind me going in, mostly Phase I and II site assessments and some regulatory compliance monitoring.

The exam has five content areas and I weighted my study time based on where my experience gaps were. Environmental science fundamentals and site assessment procedures I felt good about from day-to-day work, so I did mostly review there — maybe 15% of my total study time. Environmental regulations and compliance, and the management and communication sections, got much more time because those don't come up as much in field work and the exam tests them at a level of detail that surprised me.

I used the NREP AEP candidate handbook as my primary guide — every topic in the content outline, I made sure I could explain it at a conceptual level before moving on. I also did about 250 practice questions across the 6 weeks, which I know is fewer than some people recommend, but I was very focused on understanding the material rather than grinding through questions. Every wrong answer got a written explanation in a notebook I kept. That habit probably made 50 correct answers possible that otherwise wouldn't have been.

The exam itself was 150 questions in 3 hours — I finished in about 2 hours 20 minutes and used the remaining time to review flagged questions. The regulatory questions were the trickiest because some of the RCRA and CERCLA distinctions are genuinely subtle. Overall it felt fair if you'd actually studied the content outline versus trying to rely entirely on field experience.
