3+2 is simply a three-year junior college to two-year undergraduate course, which is essentially a junior college. But this is much simpler than ordinary undergraduate courses.
Difference: The biggest difference is that the enrollment targets of the two methods are different. Let's take the Notice of Shanghai Education Commission on Doing a Good Job in Recruiting "College-upgraded" freshmen in some ordinary universities in this city in 2022 as an example. In 2022, the enrollment targets of Shanghai's "College Entrance Examination" are mainly college graduates (including higher vocational colleges) in 2022 from ordinary universities in this city and college graduates (including higher vocational colleges) in 2022 admitted from foreign universities, including students who graduated in the spring of 2022. The "College Entrance Examination" is aimed at candidates who took the unified college entrance examination that year, and its starting point is completely different from the "College Entrance Examination". From the point of view of specialty selection and correspondence, the candidates of "upgraded undergraduate" need to choose colleges and majors according to the requirements of the general rules published by undergraduate colleges in that year, while the connection between upgraded undergraduate and undergraduate majors is basically one-to-one, which is relatively more targeted.
What ordinary college students need to test: computers other than languages. Then sign up for which school to go to (the same as the college entrance examination volunteers) and then enroll according to the scores from high to low.
3+2 Need to take the exam: corresponding to the professional courses of the university, but also take part in English (if it is an English major, take the Chinese exam) and computer. Then, the corresponding professional courses in the university cross, and the two undergraduate courses cross (generally 60 points cross, full score 100). Moreover, the transition is successful if the process assessment is met during the university period.
