We have released the 24th edition of the 3rd grade gasoline app, so please take advantage of it.
Additionally, we ask for your understanding that support for the 2023 version (this app) is scheduled to end at the end of October 2025.

The content of the book ``Automobile Mechanic Class 3 Gasoline Frequency-Based Problems and Explanations Reiwa 5th Edition'' published by Koron Publishing has been made into an app.

You can try the 10 questions extracted from the October 2020 exam completely free of charge. There are no annoying advertisements at all.

You can add "a total of 10 registration exams from March 2018 to October 2020" as additional content (paid) from this app.

Please install it once and try it out.
