It's no use. Assistant marketer is the third level of professional qualification certification, also called senior marketer. The second level is the real salesman and technician level, and the first level is the senior technician level. In most areas, the first level is not allowed. There is no compulsory examination for the certificate of marketer. Level three is useless. All college students can take the exam, and the passing rate is relatively high. Grade 2 has a higher gold content. Of course, the exam is also difficult, and there is a thesis defense.
