so cal girl,
I got an notice about a month and a half ago from Davis sayiny that my app was complete and that it was being reviewed. The UC's are very picky and since they get their pick of the best of the bunch, it'll probably take a while for Davis. I am personally gonna wait another month and then call them. The reason I say this is that they barely just started interviewing, so to call and ask them right now would be kind of pushy, especially this year with all the problems, etc. As for your question about rejections and holds, some of my friends have recieved rejections from UC's, so they are definetely rejecting people right off the bat. Also, I have recieved a hold for possible interview from UCSD. I don't know what that means. I guess it means, "just sit and pray." If you read around, you'll also find some people have been rejected from UC's after turning in their secondaries. The bottom line with UC's is that they have always been a little behind other schools, especially this year. But, they got their pick at the cream of the crop. I'd say just wait it out until it has been about a good 2 and 1/2 months, and then contact them. Hope this helps.
