"Joint Examination" is actually an unofficial name. As the name implies, it is the "joint exam", that is, multiple provinces take exams at the same time. Of course, from the perspective of historical evolution, the recruitment of provinces participating in the joint entrance examination is organized separately. The pre-announcement, outline, registration, post-scoring and interview are all carried out separately. Therefore, it can be considered that the entrance exam is just a gimmick, which saves the exam.

As the exam is on the same day, judging from the content of the questions, most of the questions are extracted from a large question bank. Taking the line test as an example, the number of questions in each provincial exam is generally 120, while the big question bank given by the joint exam is often 150, which means that at least 90 questions are the same between any two provinces.

Therefore, the distribution of test sites in the joint entrance examination is similar. The operation of this national unified proposition also ensures the reliability of the quality of the test questions, and basically converges to the national examination. This is a "unified time, unified question bank" joint exam.

Although the entrance examination is arranged on the same day in all provinces, the recruitment procedures and examination arrangements are carried out independently. Each province independently issues recruitment notices and organizes examinations independently. There will also be differences in examination policies and recruitment conditions in different provinces.

As far as the content of the public examination is concerned, most of the joint examination provinces use the same set of papers ordered by the same expert group. The examination questions of the examination subjects will be repeated, and the applied subject materials are basically the same. However, each province will also add some local elements to the test paper to highlight the local characteristics of the province.
