We have released the 25th edition of the 3rd grade gasoline app, so please take advantage of it.
In addition, we ask for your understanding in advance that support for the 2024 version (this app) is scheduled to end at the end of October 2026.

The contents of the book ``Automobile Mechanic Class 3 Gasoline Frequency-Based Problems and Explanations 2020 Edition'' published by Koron Publishing have been made into an app.

You can try out 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 2019 to October 2020" as additional content (paid) from this app.

Please install it once and try it out.
