发狂了，MSU的PS和AS

和去年申上的学弟通了一通电话，他们去年还只要一份PS。现在系统又要AS又要PS，我把PS拆开怎么读违和感怎么重，而且

AS要求的这一段：

Briefly describe key experiences that led you to graduate studies. Examples might include research experiences, internships, coursework or extracurricular activities.

PS要求的这一句：

describe how your background and life experiences – including social, economic, cultural, familial, educational, or other opportunities or challenges – motivated your decision to pursue a graduate degree.

我了个去，这不都是一回事情嘛。。。。不知道在PS和AS里有一模一样的一段话不知道行不行。

我再问问我学弟吧，看看交一篇PS能不能行。。。。。
