Can Suzhou Vocational University transfer to another university?

Hello, I'm a student in the Department of Economics and Trade of Suzhou Vocational University. When I was a sophomore (you can also choose a junior year), I chose the junior college version, that is, I would not study in our school in the future (I won't get a diploma when I pass the sophomore exam, but I can go to other colleges for further study (Nanjing University of Aeronautics and Astronautics, the Department of Electronic Information Engineering, and the Department of Economics and Trade is relatively poor). It seems that the Department of Economics and Trade must fail the course, and the score must reach a certain point. In the third year, you can choose a self-taught book (in fact, a teacher will give you a class, or you can sign up at the self-taught office, and all of them will come out with a self-taught diploma, but the self-taught book must be taught until the fourth year). From the third year, you have to pay the normal tuition fee +6000 yuan/year for self-study counseling, and the school curriculum will continue to graduate normally in the third year, which means that you will take the self-study exam while studying in the third year. We haven't been in contact with those who have been promoted to undergraduate courses, but some students seem to be in the 3+ 1 mode and went to Suzhou Institute of Science and Technology in the last year. Maybe it is.
