How difficult is it for supervision engineers?

The passing rate of supervision engineer's examination is about 30%. Judging from the passing rate, the supervision engineer still has some difficulties. Why the supervision examination is difficult is mainly reflected in the following points:

1, a wide range of knowledge:

There are four subjects in the supervision engineer examination, and candidates are required to pass all the results within four years. Supervision engineer is a liberal arts exam with a wide range, which requires candidates to spend a lot of time and energy to remember and understand. At the same time, the three controls also need to go to many calculation parts, which will also increase the difficulty.

2. Working hours are not allowed:

Most of the candidates who choose to take the supervision engineer exam belong to on-the-job candidates, and they don't have much free time to study except their daily working hours.

3. Lack of professional guidance:

In order to improve the passing rate of their supervised exams, many candidates will buy a lot of textbooks to study at the beginning of preparing for exams. However, this practice of "swallowing dates" without making any choices is not very helpful for preparing for the exam. It is still necessary to prepare for the supervision examination through professional guidance, and allocate time and energy reasonably to achieve twice the result with half the effort.
