Got my results today — passed! Wanted to write up what actually made the difference since most study advice I found online was either vague or trying to sell something.
What worked for me:
The most useful thing was drilling "bar to psi" until I genuinely understood why each answer was right, not just which one was right. I stopped doing marathon study sessions and switched to 45-minute focused blocks.
The practice tests here matched the real exam difficulty closely. I found questions on "psi exams" especially well-calibrated — the format and wording were similar to what I saw.
What didn't work: reading the official textbook straight through. Too dense. I'd read a chapter, take a practice test on just that chapter, review every wrong answer, then move on.
Final score: 83%. Time I had left over: about 28 minutes.
Happy to answer questions. You've got this.
Same boat a few months ago. Here's what I'd tell myself:
The PSI exam is more concept-focused than the study guides suggest. They test whether you understand bar to psi, not just whether you can define it.
My tip: when you see a scenario question, mentally walk through it step by step before looking at the answers. The wrong answers are designed to catch people who jump to conclusions.
Good luck — the fact that you're doing this level of prep means you're going to be fine.
