Generally between 100% and 120%. Because the Ministry of Education stipulates that the enrollment ratio of ordinary colleges and universities generally does not exceed120%; On the other hand, in order to successfully complete the enrollment plan and ensure the enrollment quality, the enrollment ratio determined by the enrollment institutions is generally between 100%- 120%.

China's college entrance examination enrollment has a provincial-level recruitment process, first filing, and then admission to the school. Investment ratio is to solve the problem of how much investment is appropriate. Taking the enrollment institutions as the unit, it is the ratio of the number of enrollment plans of the same batch and the same nature to the number of candidates' files.

In order to reduce the risk that candidates may quit their files after applying for the exam, improve the quality of school enrollment and carry out enrollment work efficiently, some colleges and universities stipulate in their enrollment regulations that the enrollment ratio of their schools is 100%. Its specific meaning is to strictly follow the enrollment plan and not vote for more than one file. As long as all aspects of candidates (moral, intellectual and physical) meet the admission requirements, especially professional adjustment, colleges and universities will not quit; In other words, as long as you get into the file, it means that you are basically accepted. This is really based on candidates, not on schools; It is a concrete manifestation of truly respecting candidates and treating them equally.
