The available data for the current situation of admission process were analyzed by Chinese province as one of the characteristics of the college entrance examination system in China. The analysis aims to clarify the actual situation of disparities by province, which was often pointed out in previous related studies. As a result, the following three points were identified. First, even if the same exam questions were used in highly selective universities, differences in average passing score rate can be seen among the provinces. Moreover, these differences were almost fixed and did not depend on the year. Therefore, as one of the causes, we consider that each province has differences in the education level. Second, the quota allocation did not correspond to the number of examinees in each province; therefore, the quota system itself may create a gap. This is a serious problem because this obstacle cannot be overcome by students’ efforts. Third, students of provinces that prepare their own exam questions tend to have the advantage in the selection process. Because the exam questions were created independently, it is not possible to easily compare the difficulty of the test questions with those of other provinces, which avoids some criticisms. Most of the provinces that have created their own exam questions are the advanced Chinese provinces with many universities, including highly selective and prestigious universities. These prestigious universities could be entered more easily by allocating capacity to the local students.
