GaTech和UMICH的ECE PhD是不是都不用寄送材料？

如题，并没有找到寄送地址，也没有看到说要mail official transcript，而是说：
Transcript (unofficial or official) for eligible degrees (only Physics, Computer Science, and all Engineering fields)
Official transcripts are welcomed but are only submitted if an acceptance has been offered.
但问题是FAQ里又有关于材料寄送的问题
有人问过小蜜吗？
