NCSU什么时候最后答复

如标题。他家ad最晚可以什么时候答复？

不是发了邮件说是6/15吗?
官方邮件如下:
Graduate applicants admitted to NC State University usually want to know if there is a deadline for accepting admission.

The Computer Science graduate program requires students admitted to a graduate degree to indicate their intention to enroll
no later than June 15
This is accomplished by paying a deposit of $300, which is credited toward the first semester's tuition (or toward student fees, for those who have departmental aid awards). The deposit is non-refundable, and may be deferred if you defer enrollment to a later term. However, CSC will not approve a deferral request unless an advanced deposit has also been paid by the deadline stated above.

Admittees confirm their intent to enroll with two actions:

1) completing the enrollment form linked from their online decision letter once it is available to them, and

2) paying the enrollment deposit by June 15.

The Graduate School further explains the deposit and process of accepting admission in your admission letter. Related questions should be directed to the appropriate Graduate School contact provided in that letter.
