If you have received the secondaries you would notice that they do not begin interviewing until mid october or november. UCLA doesn't start till november. Davis I think starts in Mid October....UCSF starts in mid october...UCI hasn't even sent their secondary to ANYONE yet!!
So don't worry about it...
I dropped by UCSF admissions last week (was going in to volunteer to host) - they said they won't start having interviewees on campus until mid-October. Don't know about the other UCs.
