Messed up on UC application

Applying to College
1

<p>I accidentally put 2 semesters of American Government/Civics when it's really 1 semester of Government and 1 semester of Economics (required to graduate).</p>

<p>I emailed the UC email at the top right of the UC application page, but is this enough? Or will I have to go as far as writing a letter to each UC I applied to?</p>

<p>That should do it but you need to be sure. So call and ask.</p>
