急急急，Gatech AD后这邮件神马意思啊？小伙伴们看进来

Gatech AD后今天收到这个邮件：

The admission link should now be working. Please select if you are choosing to accept or decline our admission offer through the status checking page.

p.s. The system make 24 hours from the time this email is sent.

这神马意思啊？难道要今天就做出去或不去的决定？？？但是这么早还有很多学校没出啊？？？decision letter不是写的4.15前做出决定就行了吗？
