Of course, the training class is ok, and this is where I apply for the course exam. But in Chinese mainland, after all, this certificate is an admission class, and it is difficult to pass the exam. If you are not good at studying, it will certainly be difficult. If you don't know how to choose a course, you can consult your teacher, who will recommend it for you according to your situation. Moreover, there are also a brush question bank and a fire-fighting 3D practical operation system, as well as high-quality teachers giving lectures on the spot.
