Changing major after applying for freshman year

<p>Hello, all</p>

<p>I recently applied to the UC's, but I already have some concerns.
I applied to UCI as a music major and my alt. major as undecided. Can I change my primary major to undecided? or is it impossible to do it now since I already applied. :(</p>

<p>thanks all</p>

<p>Once you’re accepted, you can change your major online, or you can do it at orientation.</p>

<p>For music major, I need to send in a pre-screening cd by jan. 8, and I need to audition to get in. If I don’t send in a pre-screening, then do I get rejected by UCI also? or do they consider the alternative major?</p>
