College-upgraded undergraduate (3+2 mode) generally refers to junior college students who take the college-upgraded undergraduate exam in their junior year (when they graduate, they must be fresh graduates to take it). Generally, they are promoted to the undergraduate course of the original school or take the unified examination of other schools, and then go directly to the undergraduate course after graduating from college. The final graduation certificate is the undergraduate diploma of general higher education.
Undergraduate courses are divided into two categories: the first category is general higher education undergraduate courses (also called unified recruitment undergraduate courses), and the examination objects are limited to college graduates from all provinces, municipalities directly under the central government and full-time ordinary colleges and universities (unified recruitment).
The names of individual provinces are different. For example, Hebei province is called the professional edition of colleges and universities, Guangdong province is called the professional edition of colleges and universities, Jiangsu province is called the professional edition of colleges and universities, and the rest provinces are called the upgraded edition of colleges and universities.
The second category is adult higher education, which consists of self-taught examination, adult college entrance examination (divided into amateur and correspondence learning methods), online education (distance education) and open university (formerly RTVU).
