There is little difference between undergraduates and junior college students, but now everyone is thinking in inertia, thinking that only those who have not passed the undergraduate exam will attend junior college students, so natural junior college students will be inferior to undergraduates. In addition, in society, schools do not attach importance to junior college students, and now schools can't see how to attach importance to undergraduates, even graduate students and doctoral students. I have learned less and less at school now, so I can only comfort myself. At school, we just learn a learning method and get a diploma.
Many universities have both junior colleges and undergraduate courses, as well as master's and doctor's degrees.
