Gallatin or CAS Undecided?

<p>I'm confused about my major and I haven't really decided yet. So I applied to CAS, undecided.
I've already submitted by application and supplement. But I've been reading a little more on Gallatin and I think I'm better suited there than at CAS.
I'm not sure what I should do.
And if I want to switch, is it still possible? If it is, how do I do it?</p>
