Thanks, @iulianc . That’s what I thought! So if she is accepted early on to another school, then we may have to wait (and potentially sacrifice housing choice) to see if she hears from her top choices. That’s what I anticipated.
@Gumbymom yes, she is applying to other schools as well, but really only interested in the 5 I mentioned. 
UC Riverside is her safety school. She’s currently working on the UC application since the Cal Poly applications won’t be out until October.
