The training plan after admission is different from the second table, but there is little difference. Usually, courses are set up independently, and classes are taught from the second table, and there is no difference in the final diploma. Many B-Form students have been admitted to graduate schools, even worse than B-Form students, but the study style of some majors is not very good, which is difficult to estimate.
As for joint education, each school has its counterpart foreign schools, but I have hardly seen any students go abroad in this way for so many years, because they have to pass TOEFL and IELTS exams first. In fact, graduation now depends not only on majors, but also on ability and family conditions, and it has nothing to do with whether you have two B-types. For reference only.
