Me neither, I haven't got anything yet. I know the people from Irvine Valley College already got them, but they got their admission decision in the beginning of March (wayyyyy earlier than us, becoz it's a CC in Irvine).
I got mine like a week ago and the website offered me admission around the 21 of March. I think it comes from the particular school you belong to. My letter had the return address as "Donald Bren School of ICS".
It was scary because it looked exactly like the letter I got for rejection two years ago unlike the package I got from Davis recently.
