Does UCLA confirm class schedule changes?

<p>Hi everyone. I'm accepted to UCLA as a freshman for the bio major. I had dropped a class at the start of senior year and when I called I was told to send a written letter to the UC System Processing Center and they would then forward the notification of the dropped class to the campuses I applied to. I never received a confirmation though from any UC campus or the processing center about receiving my letter. </p>

<p>Is there a way to confirm that UCLA knows I had dropped this class before accepting me?? The office of admissions website says "Notify us of any changes" and I just want to be sure they know I already notified them. I don't want them to freak out when the receive my transcript and then I have no proof other than saying I sent a written letter (which they told me to do).</p>
