I agree with the consensus above - save the dough and go to a CSU. About the middle class scholarship - it is only for tuition and has been inconsistently funded - and the rules to qualify have changed significantly since its introduction - articles like this are always in the press.

Even the UC site hedges about how much you’ll get.

As a parent, it is really frustrating not being able to count on a consistent award year to year. We got about 20% of CSU tuition when my son was a freshman and nothing since.
I wouldn’t count on getting a dime - that way you won’t be disappointed.
