We have released the 24th edition of the 2nd Class Diesel 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 contents of the book version of ``Automobile Mechanic 2nd Class Diesel Frequently Asked Questions and Explanations 2020 Edition'' published by Koron Publishing have been made into an app.

You can try it completely free of charge with 12 questions extracted from the March 2020 exam. There are no annoying advertisements at all.

You can add "a total of 12 registration exams from October 2017 to March 2020" as additional content (paid) from this app.

Please install it once and try it out.
