有关ASU EE网申时候的小方向问题

LZ想申请ASU的MSE@EE。网申的时候看到要选择小方向，而且说录取后不能改方向。原文如下：To apply to the MSE program, you must choose an area of specialization and submit a statement of purpose using the form below. The area of specialization cannot be changed after you have been admitted.


[size=1.1em]同时，他家的Degree Requirements 如下:

[size=1.1em]at least five EEE courses
at least three EEE 500-level courses
at least two courses outside the area of specialization
at most one EEE 590 Reading and Conference or FSE course
at most two 400-level courses

[size=1.1em]可以看出其中也没有提到至少要选几门小方向内的课，只说了at least two courses outside the area of specialization。。。难道500level的课就是小方向内的？

[size=1.1em]现在的问题就是申请的时候选的area of specialization到底对选课有没有影响？如果不影响的话为什么还必须我们申请的时候选择小方向？

[size=1.1em]

[size=1.1em]求申请过ASU的大神们能给小弟解解惑~~~
