UCI/ UCSD appeal?

I applied to 8 schools. 4 UCs and 4 cal states. I’ve heard back from 7 (still waiting on Merced) so far, rejected to all UCs and rejected to cal states bc I don’t qualify to be in the “local area”
I’ve only been accepted to cal state la.
I plan on writing an appeal to both uci and ucsd. (my dream schools)
could I get an info on your experience w appeals and how to make an appeal letter stand out? thank you
