This might make the question “are you premed” more important.
Biology is a major where some form of graduate school is relatively likely regardless of whether you are premed or not. “Some form of graduate school” in general makes it best to avoid debt for undergrad if you can, and even better if you can leave some $$ in the bank for some form of graduate program.
On the other hand, some of your out of state options might be just as affordable as UNC, depending upon what your budget is and what sort of aid you were offered.
And one daughter did not figure out what to do with her degree in biology until way later than high school. This is normal and entirely okay.
