Also realize that if you did not hear from either school, do not fret. All UCs have until the end of March to release their acceptance offers. Last year, I called UC Irvine on this early acceptance (as my daughter received one February 1st and my son did not). They said they decided to release offers early and will trickle and continue to do so until March (last day happened March 22nd in 2011).
SFMom3 will do her research and will try to give you a rough estimate on exactly when each UC acceptances will be released online. For example, UCLA is usually the second Friday in March at about 5:00pm.
Again, do not freak out if others heard from UCR and UCI, and you did not. Save your energy for the real anxiety in March. No lie. --SFMom3
