Application Changes?

<p>I noticed that I added 2 extra semesters of a music class on accident, and I was wondering when is the latest I could make changes to my application? The admissions offices of some schools told me to wait for some online portal information, but i've only received the login information for one school. I tried calling the admissions offices again, but they are closed until Jan 2. Should I just wait until January to call and make changes to my application, or will it be too late?</p>

<p>Thanks</p>

<p>Better January than February. You obviously can't contact them while they're closed, so as soon as they open again is your best bet.</p>
