Okay so I've been lurking here forever but I finally have to post because I passed last week after two failed attempts and I want to help anyone else who's stuck. My first two scores were 68% and 71% — both just under the passing threshold — and I was genuinely starting to wonder if this cert was even worth pursuing. What changed everything was actually slowing down on the procurement regulations section, which I'd been skimming because I figured it was straightforward. It's not.
The biggest shift for me was using a structured ESPC study guide instead of just reading through my notes randomly. Having topics organized by weight made me realize I was spending way too much time on stuff that barely shows up. I'd also recommend finding a solid ESPC practice test and timing yourself strictly — the real exam's pacing caught me off guard both previous times.
Anyone else here studying for ESPC right now? Happy to share more specific exam tips on the energy savings performance contracting sections if it'd help. That's where I personally lost the most points early on.
