Preparation for the Mechanical Maintenance Skills Certification, Mechanical Systems Level 1, Practical Exam. Past exam questions are published on the website for three years, but practical exam materials (photos, diagrams, vocabulary, etc.) are kept confidential and not released, making it difficult to understand past questions and prepare effectively. I have compiled actual exam questions for eight years (2015-2022). You can efficiently advance your studies by focusing on the topics with a high probability of appearing on the exam. * Sent on CD-R. ★ I took the 2021 exam (held on January 16, 2022) and scored 92 points, with 68 out of 71 questions correct (95.8%). Preparation materials: A4 size, color, 33 pages Bonus: A4 size, color, 5 pages (summary table) If you also want the [Theory] materials (860) sold separately, please purchase the [Theory + Practical] set for 1600 yen (340 yen cheaper). [Customer Feedback] I am surprised by the in-depth content. I feel like I can pass. Thank you very much.
