What's the difference between Xi 'an Cost Officer Examination, National Examination and Provincial Examination? What is the difference between national textual research and provincial textual research? Well, the national examination is a provincial examination of the national unified examination, and it is also graded as 123. In fact, it is better to take the national unified examination, because it is very troublesome to change the certificate of provincial examination in the future, and the domestic examination is generally the national examination. There are two national unified examinations in Shanghai and Beijing every year, and the certificates issued by these two cities are all common in the country. Looking forward to receiving favorable comments ~
