Anyone found good free GD&T study resources besides the obvious ones?
I've already gone through the standard "GD&T" results on Google and most of it is just selling prep courses. Looking for actual free resources.
What I've tried:
- Practice tests here (solid, especially for GD&T - Geometric Dimensioning and Tolerancing Certification)
- A few YouTube channels but the quality is all over the place
- Reddit threads from 2+ years ago (some outdated)
What I haven't tried yet:
- The official GD&T study guide — is it actually worth reading cover to cover?
- Library resources — anyone actually found useful materials there?
- Specific YouTube channels that cover GD&T exam well
I don't mind paying for something that's genuinely better than free, but I want to max out free options first. Budget is tight.
What resources did you use that you'd actually recommend?
If you're looking for a starting point, the free gdt geometric symbols notation is worth trying — the questions closely match what you'll see on test day.
Passed GD&T 6 months ago. Happy to share what I remember.
On the "GD&T exam" stuff specifically — I found the practice tests here were actually harder than the real exam on those questions. Which was great because going in I felt more prepared than I needed to be.
The time pressure is real though. I came in with maybe 8 minutes to spare and that was after skipping the ones I wasn't sure about and coming back.
Don't try to cram the night before. Seriously. Last-minute stress makes you second-guess things you actually know.
