各位大大好:
第一次發文，排版請見諒....
小弟目前已經完成線上申請，而且也Submit了
不過，Purdue系統裡面的Supporting Documents
裡面有這一段話:
Additional documents are required to support the application. Supporting
documents should be mailed directly to the graduate program to which you are
applying. Supporting documents include the following, unless specific
instructions are noted in the "Completing the Application" section of this
page:
然後下面就包括
1.Official transcript
2.GRE 和 TOEFL
3.推薦信
4.SOP <==有問題是這個
前三項可以理解，不過SOP也要用寄的話那我當初填
線上申請的是輔助的嗎??........
懇請線上的各位幫忙解惑，小弟感激不盡!!

我SOP只有填線上的，最後有被確認完成申請。實體寄送，只有ETS的成績和自己寄送的彌封學校成績本

我自己有寫信去問 以下是回答we require 2“official" transcripts and a“copy"of your diploma(s).
