Should I call each UC admissions office?

If I have changes (dropped a course) for Spring 2012..but I already submitted my TAU..
Is it okay to call each UC campus admissions office to report the change?
Or I can only email them?</p>

<p>I believe you can go back and redo your TAU..</p>

<p>You can still update your TAU, but since it is past the priority deadline there is no guarantee the updated information will be reviewed. </p>

<p>It depends on the campuses you applied to for example, Berkeley wants an actual letter through snail mail, UCSD wants you to fill out a form here <a href=""&gt;;/a> . It would be best to call up (or visit the admissions websites) the campuses you applied to and ask what they require you to do.</p>
