Passed CRP on my second try — here's what finally worked

Same experience here. I work at a MRF and assumed hands-on knowledge would be enough. The commodity markets section wasn't something I could fake my way through. Ended up buying the ISRI study guide and it made a real difference.

I passed on my first attempt but it was closer than I'd like to admit — about 74%. The contamination rate calculations were something I practiced with real numbers from work, which helped a lot. Definitely not a test you can wing.

The pricing and markets section is legitimately hard if you haven't dealt with commodity trading. I'd recommend looking at actual LME data and understanding how ferrous vs non-ferrous pricing works. That clicked for me about 3 weeks before the exam.

Congrats on passing. I'm 9 weeks out right now and the electronics recycling regulations section is killing me. There's so much variation by state, it's hard to know how deep they go. Did you notice a lot of questions on e-waste specifically?

Man, this hit close to home. I failed my first CRP attempt in September by 11 points — almost exactly your situation. Thought my background in ferrous grading would cover the gaps, but the exam just destroyed me on RCRA requirements and the Basel Convention stuff. I'd barely touched the regulatory modules because honestly I assumed that was the "book knowledge" part that didn't matter much in practice. Wrong.

What I changed the second time was forcing myself to actually sit with the material I hated. The market economics section — commodity pricing cycles, global scrap flow, how currency fluctuations affect export markets — I'd glossed over all of it the first time. Second attempt I made myself do timed crp practice test questions specifically on those weak areas until I stopped guessing and started actually knowing why the right answer was right. That distinction matters more than I expected on test day.

The other thing that helped was stopping myself from explaining away wrong answers with "well in my yard we do it differently." Real-world experience can actually work against you if you've picked up regional habits that don't match the ISRI framework. The exam tests what the standards say, not what 15 years on the floor taught you.

Thanks for this thread, it's exactly what I needed to see right now. I'm about three weeks out from my retake and just pulled a 78 on the crp/questions/composting organics recycling section which felt pretty good considering I bombed that whole area last time. I've been drilling practice questions every night instead of just rereading the study guide and honestly it's made a huge difference in how fast I recognize the regulation stuff.

Planning to sit for it in early August. I'm not feeling 100% confident yet but I'm way more prepared than I was in March. The market economics questions still trip me up sometimes but I figure a few more weeks of targeted practice and I'll be ready. Fingers crossed this is the last time I have to do this.

Congrats on passing! I can relate to this so much. I work full-time at a MRF and have two kids, so my study time was basically 30 minutes on my lunch break and maybe an hour after they went to bed. What helped me was getting really specific with practice questions instead of just re-reading the materials. I spent a lot of time on the organics side of things using crp/questions/composting organics recycling and honestly it covered gaps I didn't even know I had. The regulations piece was brutal for me on attempt one too.

Second time around I wasn't trying to memorize everything, I was trying to understand the why behind each rule. Big difference. If you're working full-time and cramming for this, don't skip the economics and policy sections thinking your field experience will cover it. It won't. The exam doesn't care how many hours you've logged on a sort line.

Honestly the schedule thing was what got me the second time around. I've got two kids and I'm pulling 50-hour weeks at the facility, so I couldn't block out three-hour study sessions like I did before. Instead I did 20-30 minutes every morning before anyone else was up, just grinding through practice questions on my phone. It's not glamorous but it adds up fast. By the time I hit the exam I'd done probably 400 questions and the regulations stuff that killed me in March wasn't scary anymore.

If you're in the same boat just be consistent and don't skip days thinking you'll make it up on the weekend. You won't. The market economics and compliance sections are where points go to die so focus there first, especially if you're like me and figured field experience would cover the gaps. It doesn't. The exam doesn't care how many years you've been doing this, it wants to know you understand the why behind the rules, not just what you do on the floor.
