official document

I registered in an Australia university and recently Graduate Office asks me to arrange official documents from China to them directly from university (They have received those documents from China but not from university). If they found the documents I provided is a little bit different from the documents send directly from university, I will be in big trouble. Could you tell me how I can avoid the tragedy? To tell the truth, I do change a little bit the transcript, for example, from Communist Party History to China History, and delete some courses which are irrelevant to my applied program; this is all I have done.
