The professional qualification certificate of investigation analyst must be trained by the institution designated by the Statistics Bureau before it can be registered. Those who pass the exam and finally get the certificate can't register themselves.

I also studied statistics and passed the intermediate level. In terms of usefulness, some of the contents will be close to the actual work, but after all, in the long run, it is ok to have a certificate that has just come out for 4 years.

By the way, which school are you from? It's inconvenient here. You can leave me a message.
