| Mistake | Consequence | |---------|--------------| | Using outdated PDFs (2015–2018) | Missing newer tools like digital torque meters. | | No Korean labels | You won’t understand the test proctor’s instructions. | | Blurry images | You cannot distinguish fine parts (e.g., caliper lock screw vs. depth probe). | | Ignoring safety rules | PDFs often skip safety; in the real test, incorrect tool handling = fail. |
