First of all, your friend said that the school that didn't get into the exam may be adult education, and you can't take the civil service exam with an adult education diploma. Second, Wu Zhi didn't let you go for an interview, which means you weren't accepted by them, but Bayinguoleng Vocational and Technical College accepted you, which means you were accepted by this school.

What you need to pay attention to is that all the schools you are attending now belong to the unified recruitment diploma, and the treatment of candidates taking the college entrance examination is the same in universities. Schools that register directly without exams belong to adult education diplomas.
