4.9/5
from 400+ reviews
Marcus T.
Denken Exam learner
“While preparing for PRIMARY-SECONDARY, I keep a small list of mistakes from Power Systems. Reviewing why each answer went wrong keeps my study sessions more focused than simply rereading notes.”
Grace L.
Denken Exam learner
“Great PRIMARY-SECONDARY prep. Denken Exam was clear and easy to use!”
Sofia L.
Denken Exam learner
“For PRIMARY-SECONDARY, Electrical Machinery and Applications was the area I kept postponing. Breaking it into a few practice questions at a time makes the material much easier to revisit after work.”
Dana W.
Denken Exam learner
“My PRIMARY-SECONDARY routine is simple: one timed set, a short break, then a careful review of Law Safety and System Management. The explanations show whether I understood the idea or just guessed well.”
Victor S.
Denken Exam learner
“The PRIMARY-SECONDARY practice questions kept my review focused.”
Amara K.
Denken Exam learner
“I use lunch breaks to review Electrical Theory for PRIMARY-SECONDARY. Short sessions work better for me because I can focus on one weak area without trying to cover the whole syllabus at once.”
Leo F.
Denken Exam learner
“The hardest part of PRIMARY-SECONDARY prep for me is keeping similar ideas in Power Systems separate. I now write one-line comparisons after each practice set, which makes the next review much clearer.”
Nadia F.
Denken Exam learner
“Denken Exam made PRIMARY-SECONDARY prep simple and easy to follow.”
Jonas P.
Denken Exam learner
“I am still working through PRIMARY-SECONDARY, especially Electrical Machinery and Applications. Going back through missed questions slowly has shown me which details I rush past when I practice under time pressure.”
Rosa M.
Denken Exam learner
“PRIMARY-SECONDARY review felt much more manageable with these tools.”
Recorded customer testimonials
“The practice questions are incredibly helpful. They're closely resembling the real exam scenarios, which is perfect. With detailed explanations provided, studying has never been this efficient.”
“The well-structured practice questions help me prepare for the exam conveniently.”
“Thanks to the well-organized practice questions, I was able to tackle my exam preparations with ease. The questions are thoughtfully designed to closely resemble those in the actual exam.”
“the practice questions are helpful similar to the topics covered in the real exams i love the detailed explanation provided right after each question”
“The practice questions, key study notes, and supportive staff all help me pass the exam. The best thing is the questions are well structured and similar to the ones on the exam.”
“The practice questions mirrored real exams with comprehensive explanations.”
“Can’t I Just Study on My Own?”
Of course you can. Any exam can be prepared for independently. But you’ll spend weeks extracting key concepts from dense manuals, guessing which topics are actually tested, and hoping you covered enough.
Or you can let our full-time exam team do that heavy work for you — so you can focus on practice, pass on your first attempt, and spend your evenings with friends and family instead of buried in textbooks.
- Syllabus already distilled into study notes
- Skip weeks of sorting through manuals

FAQ
Common questions about Second-Class Electric Chief Engineer 電験二種 (Primary + Secondary)
Is this MCQ set a simulation of the secondary examination?
No. The secondary stage is written/descriptive, so multiple-choice items check supporting knowledge only. Use the integrated task to practise full written derivations, explanations and safety/management reasoning.
Can I take the secondary examination before passing the primary?
The published structure allows the secondary only for same-year primary passers and those exempt from the primary. Confirm current eligibility and exemption rules with 電気技術者試験センター (JETEC).
What calculator may I use?
The published rules allow four arithmetic operations and square root. Function, programmable/expression-storing and printing calculators are prohibited; the device must not make sound and you must bring your own. Re-check the current rule with JETEC.
How long do primary subject passes last?
The published subject-pass system allows a passed primary subject to be exempted by application in the following two years. The secondary has no subject-pass system; a primary pass also exempts the next year’s primary if the secondary is failed. Confirm current rules with JETEC.
What should I prioritize in law, safety and system management?
Focus on supervisory duties, inspection and records, safe isolation and verification, protective grounding, arc-flash prevention, and coherent fault/protection reasoning. Do not memorize exact legal thresholds from old notes; confirm current requirements with JETEC and the current official legal text.
What am I paying for, and why choose Premium over free resources?
When you’re preparing for an exam, the cost goes beyond study materials. It’s the evenings spent searching for answers, the uncertainty about whether you’re covering the right topics, and the possibility of paying for another exam attempt. Premium gives you a focused way to prepare. Practice questions and explanations help you check your understanding. Wrong-answer review and progress tracking show where to focus next. Flashcards, spaced repetition and timed mocks help you revisit difficult material and practise answering under pressure. The goal is to make your limited study time count—and build confidence from what you can actually answer, rather than how many hours you’ve spent reading. Better preparation can help reduce the risk of a costly retake and the extra time away from work, family or other goals. Think of Premium as an investment in your preparation and professional development: one organised system to help you use your time more effectively and approach exam day with greater confidence. Choose the certification and access period you need, with a one-time payment and no recurring subscription.
