Totally agree with the above posts that an $85K per year undergraduate education is not worth the expense. Not even at USC.
And I mean this in a constructive way, but consider what you would like your child to learn and experience in college. My thought is that it is great for them to stay within a budget and make their opportunities as they figure out what path they want to pursue. Not that if they want something, their parents will make sacrifices to fund them. Especially as your daughter has so many great options.
Finally, in our experience (last of 3 in college!) most kids change their goals, direction through college. As they should! So keeping options open financially for grad school or summer programs is really wise.
