关于Cornell网申concentration和specialty的问题

很抱歉问一个前人问过的问题，虽然地里去年有人问过，但没有留下答案。

问题是关于Cornell网申Academic Information 2里的一项。问你的concentration和specialty各是什么。我申的CS，为什么concentration里
Computer Science会和Artificial Intelligence并列？还有那个2nd choice，3rd choice是问你过去的还是将来可能感兴趣的？

如果我是搞AI的，是不是concentration应该填Computer Science，然后specialty填Artificial Intelligence？
还是都填Artificial Intelligence？

同问啊！

最近得到了Cornell小米的回复，解释如下：

Dear XXX,

A concentration is the main area in Computer science that you are interested in, such as AI, systems, theory etc.  The specialty is the area with in the concentration that you are interested in. For example:  within systems you might be interested in databases, networking, or OS, just to name a few.

Thank you for your interest in Cornell.
