電験３種 機械 過去問・選択肢シャッフル版

About this app

This app allows you to solve past questions from the Class 3 Electrical Engineer Examination ("Machinery") with shuffled answer choices. You'll learn by the content of the questions, not just the answer numbers.

When repeatedly working through past questions, you might memorize the answer number ("this question is number 3"). This app changes the order of the answer choices each time a question is presented, so memorizing numbers is pointless. You'll need to read the question and the choices each time before making a selection.

[Included Content]
・From 2009 to the first half of 2026 (22 exams, 18 years' worth)
・182 past questions focused on text-based problems
・Displays the correct answer number and source after answering
Calculation problems requiring paper and a calculator are not included. The intended use is to use textbooks and a calculator for calculations, and this app for memorizing terminology, principles, and regulations.
