What's on the real exam (and what these questions mirror)
The PE Mechanical exam is 80 questions over a nine-hour appointment, closed-book, with the on-screen NCEES Reference Handbook as your only reference. You sit one of three depths:
- HVAC & Refrigeration — psychrometrics, equipment, heat transfer.
- Machine Design & Materials — mechanics of materials, fatigue, components.
- Thermal & Fluid Systems — power cycles, fluid mechanics, compressible flow.
The questions in this free quiz are written to those specs and at exam difficulty — so the practice counts, instead of being easier-than-real warm-ups that flatter your score.
What your score here means
This is a quick gauge, not the full picture — a handful of questions can tell you whether a depth feels within reach, but it can't map every weak area. The real diagnostic (inside the trial) ranks all your weak areas against the spec and turns them into a plan. Treat a strong score here as encouragement and a weak one as a signal of where to dig — then go deeper.
How to actually prepare (the short version)
The candidates who pass don't out-read everyone — they out-practice them:
- Diagnose your weak areas before building a schedule.
- Make problems the main event; return to theory only on a miss.
- Rehearse the closed-book Handbook until navigation is automatic.
- Practice timed so your pace holds for the full day.
That's the whole method in how to pass the PE Mechanical exam, with the timeline in how long to study.
