【Type 1 Mechanical】 This is not the official exam, but past questions and explanations from the training course's certification test. It covers the two subjects of academic knowledge and safety management for four years, from Reiwa 4 to Reiwa 7 (2022-2025). These were distributed at a study session, but I'm selling them because I don't need them. "Just keep repeating the past questions." That's the bottom line. You just need to repeat them and let your hands remember.
