Financial aid for Pre-College Programs in California

<p>I'm interested in attending a pre-college program in california that would give me college credits and give me a leg-up in admissions.</p>

<p>I've been looking at the Summer Discovery which is offered at UCSD, UCSB and UCLA.
I've also looked at the summer program at USC.</p>

<p>The only problem is the cost (7k+ for 6 weeks!).
They all claim to offer financial aid, but how likely is it that I would actually receive any? I could only go if the costs were lowered to a max of 2k. My dad (who I don't live with) makes a decent living as a teacher but my mother (my guardian) is unable to work due to a physical disability.</p>
