The school’s own net price calculator is much more specific to your financial situation (assuming accurate data), so it is much more likely to reflect what the school will offer you than a secondary averaging reported on some other web site.
So if you are ok with a $10,000 net price (which you can cover with a federal direct loan and some work earnings), and USC is a otherwise suitable school for you (in terms of academic offerings, etc.), then go ahead and apply.
