Totally Understand, My Daughter graduated from USC (University Of Southern California - Private College) in 4 Years with a Major and Minor degree...
Abut the same number of seats and 50000 plus apply yearly, they can and are very selective
In 2015, USC had about 50,000 applicants, admitted about 9,000, (about 18%) and had a yield of about 3,200 (a yield of over 33%). The most selective school in California is Stanford, at about 5% of applicants. In recent years, Stanford has become as selective as Harvard, and has actually been a little more selective than Harvard in some years.
College admissions at the top tiers has become ever more selective. Even a school like University of Maryland, College Park, about 50th or 6th in the nation, and once known as a party school, now rejects more than half its applicants.
