USC CS下面的computer security track 能转到general track吗？

请问USC CS下面的computer security track 能转到general track吗？ 当时申请时三个都没选general，现在录取了一个computer security track。请问能不能申请转到general下面啊，主要目的是节约点钱。
我查了一下好像是可以互转，但是不知道学校会不会同意从这种交钱多的track转到交钱少的track。
如果可以怎么操作了？是现在就可以发邮件给学校，还是开学以后再办？
有人有类似的经验吗？
谢谢了，大米回馈。

找到答案了：
You can change your specialization only after completing your first semester at USC. However, during your first semester you may enroll courses that will apply towards your desired specialization. Please email your advisor after your first semester grades are released on OASIS to initiate the change of specialization.  Be sure to email from your USC account and include your USC ID number.

我的一个在读朋友说可以随便而且多次转，找人登记下就行
