Very reliable, but you have to measure whether it is worth it. The current market is far from good as it was a few years ago.

Let's talk about textual research first. The fire certificate examination is three subjects, practical, comprehensive and case-based. Full score 120, passing score 72. It will take three years to pass these three exams. If you just want to do textual research, you need a lot of effort. And the cost of study is quite high, ranging from five or six thousand to tens of thousands.

Besides, this year's market is about 30,000-40,000. If you are researching for the sake of hanging the certificate, I suggest you consider it carefully.
