Can the real questions of Beijing Jiaotong University's postgraduate entrance examination be found in the printing room of Beijing Jiaotong University?
It's impossible. It's illegal to suggest that you never do that. If necessary, you can go to the postgraduate forum to find other people's real questions, or you can go to a formal counseling institution to buy real questions. It is strongly recommended that you don't go to Beijing Jiaotong University to find these things. Maybe you should go to senior three for graduate school.
