Use this app to pass the electrician written test.
Previous questions to which the KEC (Korea Electrical Equipment Regulations) revision has been applied are recorded in two formats: one-question format and one test paper format.
You can check the answer in the middle only when you do not know the answer while solving the problem without looking at the answer. This is several times more effective learning than simply looking at the problem and the answer at the same time.
With the powerful scoring function, you can preview the scoring in the middle, and it is also good to analyze and supplement your weaknesses by looking at the correct and incorrect questions.
I congratulate you on your success.
