又有两个教授回了我的首封套磁。。

两个都说除非我已经拿到AD，被研究生院要了。。。不然他们项目不会招收人。。。我晕。。那是不是说套磁只能在拿到AD之后？之前没用是不是啊。。下面是教授回话：
I don't accept students into my group until they have been accepted into graduate school at OSU and have passed both of their qualifying exams. If you would like information about applying to graduate school at OSU, please see our webpages.
