Undergraduate graduates of adult colleges and universities: refers to adult education institutions that have graduated and have undergraduate qualifications (many colleges and universities now have adult education colleges) and participated in the adult college entrance examination.
The difference is that the state recognizes graduates with academic qualifications and fresh graduates from adult colleges and universities to take the general college entrance examination or adult college entrance examination, while self-taught students and online education students do not take the college entrance examination when they enter school. Therefore, it is necessary to use brackets to indicate that self-taught students and online education students are not included, because the countries of self-taught students and online education students also recognize academic qualifications.
