I agree with above that having stats on past applicants aren’t going to help you make determinations with your D in the upcoming year. A lot has changed in just the past few years. Budget issues has UC’s waitlisting and rejecting a lot of kids they’d normally have accepted. It’s been a marvel to see almost identical candidates get wildly different results within our circle of friends. Kids get into Harvard but rejected from their first choice UCLA. Kids get regents at UCB and rejected from UCD. It’s just really difficult to predict right now.
Please don’t read into invites and summer program denials. You’ll just drive yourself and your D insane. She’s got great stats but she’s going for the most competitive majors so really, none of the schools you mentioned should be considered a safety. Did you not mention UCSB? Don’t they have a top notch engineering programs too?
All your D can do is put together her best application and cast a wide net. Keep looking into private schools or OOS public schools that can offer big merit. There is nothing stressing about the UC’s can do for you. Not one single thing. She’ll get into something and I’m sure it won’t just be UCR or UCM.
