For studying for the Level 1 Mechanical Maintenance Technician certification exam. This is a set of the [Theory] materials (860 yen) and the [Practical] materials (1080 yen) sold separately. [Theory + Practical] 1600 yen (340 yen off) Sent via CD-R. [Theory Preparation] Covers 5 years of past questions (2017-2021). Explanations for why the answer is "X" are provided for all incorrect questions. For "O" answers, especially for Level 1, understanding is often difficult with just "as the question intends," so supplementary comments are added as much as possible. The scope of the Mechanical Maintenance Technician certification exam is broad, but the actual exam trends are limited, and important items are repeatedly tested. Analyzing the 2021 exam: New questions (no similar questions in the past 4 years) 27.4% Questions with the same or similar content in the past 73.6% With these materials, you can acquire the skills to pass the exam in a short amount of time. (Additional Information) * 2016 questions are also included (separate file) (Increased to 6 years from 2016 to 2021) [Practical Preparation] Past exam questions are published on the HP for 3 years, but the practical exam materials (photos, diagrams, word groups, etc.) are not disclosed due to the certification's confidentiality, making it difficult to prepare because it's unclear what kind of questions have been asked in the past. I have compiled 8 years of actual exam questions (2015-2022). You can efficiently advance your studies by focusing on the content with high exam trends. The practical exam is graded by a deduction method. The deduction points are larger than the value obtained by dividing 100 by the number of questions, and unlike the addition method, passing does not mean getting 60% correct. Therefore, it is necessary to understand the content thoroughly. * I took the 2021 exam (held on January 16, 2022) and got 68 out of 71 questions correct (95.8%) for a score of 92. [Customer Reviews] * I purchased this following the previous year (Level 2). The content was very fulfilling this time as well. I passed with ease last year, and I feel confident going into this year's promotion challenge. * I am the person who purchased the Level 1 and Level 2 Mechanical Maintenance Technician materials. They were very easy to understand and very helpful, and I was able to pass Level 1 and Level 2 last year and this year. I am truly grateful.
