I have carefully explained all possible answers and detailed explanations of the candidate questions for the 2021 skill test, including photographs and diagrams. It is perfect for self-study because it includes a double-track diagram with the points related to pass or fail, a color completed photograph, a completed actual wiring diagram, a simulation test sheet assuming general construction conditions, and a list of materials necessary for training. In addition, the basic work necessary for skills is carefully explained from the beginning by photographs and diagrams so that even those who are new to the test by themselves can easily understand it. This book is already a second class skill book, and it has a great reputation for being "simple and easy to understand" and "fast in work," so that you don't have to learn anything unnecessary about only the important points related to the pass or fail decision, so you can start practicing with peace of mind.
