2, the unit unified examination:

Communication Administration will generally send a letter in advance to all units in the communication industry and communication engineering construction units in need when holding corresponding budget training courses, which can be registered by units in a unified way, with the same follow-up process. There is a question of whether you can get a certificate in the unit registration method, depending on whether the training fee is reimbursed by the unit or taken care of by the individual.
