You answered it. UNC. Your family may support you but you know UNC costs less, it’s as good for journalism and frankly no one should pay big bucks for journalism (not a good major for outcomes) and USC is now more than $90,000 a year. That’s $400k by the time you graduate or very close to it.
UNC is not direct admit for business so that would be a hesitation. But they have a minor or other related majors should you not get in. .
But you could still get in and even if not, this is a no brainer.
Good luck.
