So I just got my BGE certification results back and I passed with an 82. Honestly didn't think I'd make it after failing my first attempt back in March by four points. That first time around I basically just skimmed the manual and thought that'd be enough — it wasn't. The gas systems and pressure regulation sections destroyed me.
What changed the second time was actually being systematic about it. I spent about 6 weeks studying, roughly 45 minutes a night after work. I grabbed a BGE study guide online and went through it section by section instead of jumping around. The biggest thing that helped me was doing a BGE practice test every Sunday to track where I was still weak. By week four I could see my practice scores climbing from the low 60s up into the high 70s, which gave me a lot more confidence going in.
For anyone prepping right now — don't underestimate the safety codes and compliance portions. I probably had 20% of my questions come from that area and my first attempt I had barely touched it. Anyone else have tips on the installation troubleshooting questions? Those still tripped me up a bit even when I passed.
