There is no official document about overlapping academic qualifications. "In principle, overlapping academic qualifications are invalid academic qualifications and cannot provide proof. Once you need to go to the Ministry of Education for academic certification, the certification center will not pass, because it is illegal to enter the university without graduating from secondary school.

In the second year of technical secondary school, the school will recruit an amateur junior college. When you can graduate after paying the tuition fee for three years, you will be told that the diploma will be invalid, because the academic qualifications overlap and cannot be used as the basis for various exams.
