UCs: drop courses

I have notified UCLA, UCD, UCSD, UCB, UCI, and UCSB earlier about dropping one of my math classes (differential equations) due to conflict scheduling with basketball practice. So far, I am accepted to UCLA, UCSB and UCI, but I haven’t received any replys/confirmations from those colleges regarding the class drop. I am worried that they didn’t get my message, What should I do?

<p>I also notified UC's of a dropped course but I didn't get any confirmation/receipt either. Does anyone know if we are supposed to?
Reflection: Did you e-mail those schools or send them letters? I sent some letters and e-mail others.</p>

<p>I sent e-mails and letters because some UCs, i.e Berkeley, don't take e-mails.</p>

<p>Bumpppppppp</p>

<p>bump again!</p>
