Finally passed CCT after bombing the blueprint reading section twice

Third attempt, finally got through. I want to write this up while it's fresh because I spent a lot of time reading forum threads like this one when I was struggling, and most of them just say "study harder." Not helpful.

The blueprint reading section destroyed me twice. Not because I don't understand blueprints — I've been a calibration tech for six years. It's because the CCT practice test questions frame things differently than what you see on the job. They ask you to identify tolerance ranges from a schematic that's deliberately ambiguous, and they penalize you for assumptions that any working tech would make automatically.

What actually helped: I stopped treating the exam like a knowledge test and started treating it like a reading comprehension test. Every question has exactly one defensible answer based solely on what's written. I did 40-50 practice questions a day for five weeks, and after each wrong answer I wrote down why the "wrong" interpretation made sense to me — then figured out why it wasn't acceptable on paper.

Passed with a 79. Not a great score, but I'll take it. The traceability and documentation sections were actually easier than I expected once I got my head straight on measurement uncertainty. Good luck to anyone grinding through this.
