Schedule Change

<p>I was planning on taking Calculus at a local community college but wasnt able to actually get into the class (scheduling conflict and the class was full by the time I could ask for it). When i found out I called the UC application processing office and they told me to simply mail in a letter to their office stating the change and they would fix it. I recently got into a UC and they requested the transcript from the community college. I emailed them and told them i wasn't actually able to get into the class. Do you think this is enough or should I call the admissions office and explain the whole situation? I was guaranteed admission by ELC so does it matter much?</p>
