What's the actual passing score for PC? Getting conflicting info

The honest answer is: it depends a lot on your background.

If you're already working in this field, the PC exam is testing knowledge you probably use daily. The "PC" sections will feel familiar.

If you're coming in from outside, give yourself an extra 2 weeks and really focus on the practical application questions.

The practice tests here are worth doing repeatedly — I did the same test bank multiple times and found new questions I'd missed each time.

For what it's worth from someone who's been through it:

The PC is one of those exams where the practice tests really do prepare you well. The style of questioning is pretty consistent. If you're comfortable with "PC" material under timed conditions, you'll be fine.

The one thing I'd add: read the question stems very carefully. They sometimes add a qualifier that completely changes the right answer and it's easy to miss when you're going fast.

Also check whether you need to schedule the exam in advance — some testing centers book up 2-3 weeks out.

Failed first attempt, came back to this thread. The consensus on pc practice test being the make-or-break area is right. Focusing almost exclusively on applied questions this time around.

Honestly I was the exact same way, I kept finding 70 vs 75 and figured the whole thing was rigged or that nobody actually knew. I almost quit twice. What finally clicked for me was realizing the percentage matters less than just drilling enough questions that you're scoring comfortably above any version of the cutoff, so a bad day or a weird question set doesn't sink you. I beat myself up over which number was "real" when I should've been studying.

The thing that turned it around was grinding through free pec electrical codes standards questions over and over until the wording stopped tripping me up. I didn't think it'd make a difference and I was pretty skeptical the whole time. It did. Don't overthink the score, just keep going.

I just passed mine last month so I can help clear this up. The passing score isn't a flat percentage — it's a scaled score, and what "passing" looks like depends on the exam version you get. Stop chasing the 70% vs 75% debate because it's honestly a distraction.

What actually got me through was hammering the code questions. I wasn't great at them at first but drilling free pec electrical codes standards practice sets every day for two weeks made a huge difference. You'll see those questions on the real thing and if you know your codes cold, the scaled score takes care of itself.

I'm in the same boat with the conflicting numbers, but I've just been aiming for 75% to be safe. Hit a 78% on my last practice run yesterday so I'm feeling pretty good about it. Definitely wasn't scoring that high a month ago, so the consistent drilling is paying off.

I've got my real exam booked for the end of next week. Honestly you might be overthinking the exact cutoff -- if you can consistently hit above 75% on practice sets you're probably in solid shape regardless of which version you get.
