What should I prepare in the early stage?
1. Practice more. The focus of the electrician certificate examination is still on basic test questions and practical examinations. These two parts are to strengthen memory, especially basic questions. Whether you can pass it depends entirely on how many questions you have practiced on the question bank.
2. Treat it as usual, although it is an exam, don’t be too nervous. Especially when you need to do a hands-on wiring, if you ignore the point connection of a wrong line of Morgan because you are too nervous, it will cause tripping or even short circuit. When serious errors occur, the pass rate is extremely low.
3. Register correctly. The examination is currently held by the Safety Supervision Bureau. You can choose to apply online through the Safety Supervision Bureau and prepare by yourself. If you don’t have confidence, you can do it through the training school, because the training school will distribute the question bank to you, and it is very useful to give relevant guidance before the exam.
