Practice for Japan's Class-3 Chief Electrical Engineer exam: study and mocks.
Everything you need for the Japanese Class-3 Chief Electrical Engineer exam (電験三種), in one app. 522 original practice questions written along the official syllabus, every one with an explanation. No sign-up, no internet connection required — start studying the moment you install it. ■ Mock exams in the real format - 76 items across all four subjects (Theory 20, Power 20, Machines 20, Law 16) - Pass/fail judged per subject: 60 out of 100 in each, just like the real exam - Jump to any question from the answer-sheet view, just like the real CBT - Pause and resume where you left off - 5 full rounds with no repeats ■ Per-subject results, the way the exam actually works - Denken 3rd Class is passed subject by subject, and a passed subject is exempt for two years - The result screen shows whether each subject cleared 60 points, so you know what is left - A high total does not hide a subject below 60 — the app says that subject failed ■ A mistake notebook that thins itself out - Wrong answers are collected automatically - Three correct answers in a row graduates a question off the list - Add your own note to any question - Filter by subject, sort by how often you missed it ■ Study by the 4 subjects and 32 sub-topics - Theory (electrostatics, DC circuits, magnetism, AC circuits, transients, electronics, measurement) - Power (hydro, thermal and nuclear generation, renewables, substations, transmission, distribution, materials) - Machines (DC, induction and synchronous machines, transformers, power electronics, drives, lighting, heating, control, information) - Law (Electricity Business Act, technical standards, their interpretation, facility management) - Short, focused sets by sub-topic, with the answer and explanation right after each tap ■ Statistics that show your weak spots - Accuracy per subject, so weak areas surface on their own - Score trend across your mock exams - Last two weeks of study time and your daily streak - "Weak-point drill" that gathers only your lowest-accuracy questions ■ And more - Random mock: choose the range and the number of questions - Bookmarks for the ones you want to come back to - Search across question text, options and explanations - Dark mode and adjustable text size - Shuffle questions and options so you don't memorise positions - Your study records stay on the device and are never sent anywhere. - The questions are original practice questions written along the syllabus, not the actual exam papers.
