All the UC’s will be Reach schools. Anything below a capped weighted GPA of 4.0 for CS will make it a difficult admit.
Some admit numbers based on the capped weighted GPA and not major specific. For CS, expect lower admit rates and higher required stats to be competitive.

Spending $65K/year to attend a UC is crazy. If you want to come to California, look at the Cal states which are about $25k/year less than the UC’s and will still give you a great education.
Cal state Fullerton, Cal Poly Pomona, Cal state East Bay, Cal State Long Beach might be good options but if your parents are focused on prestige than probably not worth your time or money applying.
Best of luck.
