This application allows you to check past questions and answers for the Class A and Class B Chief Gas Engineer Examinations.
The content is based on the "Gas Chief Engineer Examination Questions and Explanations (2024 Edition)" published by the Japan Gas Association, and allows you to check past questions and answers.
We hope that this application will meet the expectations of those who are aiming to obtain the qualification of a Chief Gas Engineer.

[Regarding legal questions]
The legal questions and answers in this application are created based on the Gas Business Act and other laws at the time of the question.

[About the question format]
In the Gas Chief Engineer Examination Question Collection, questions that ask the number of correct answers, such as "How many are correct?", are subdivided in this application and made into a one-question-one-answer format. (Some questions are not made into a one-question-one-answer format.)

[About reference books]
For explanations of basic subjects and gas technology subjects, the latest "Overview of the City Gas Industry" is used as a reference book and reference pages are listed.
