ND需要纸质成绩吗

ND的网站上，FAQ里说的是：Unofficial transcripts, recommenders (at least three), the curriculum vitae, the statement of intent, and the writing sample, if required, must be submitted electronically through the gradconnect.nd.edu. Please note: All materials received by mail will be discarded.
其它关于成绩的地方没找到，这意思是说申请时不需要纸质成绩吗？谢谢！
