Her older brother went to UNC. That made her a legacy. Out of state students pay higher tuition.
My sister, who lives in Maryland, went to UNC. Her daughter was told that there are more qualified legacies that apply out-of-state than they can legally admit.
Her daughter (my niece) got in and graduated from UNC. She was at the top of her class in a Maryland high school and had a ton of activities.
If she had not been admitted, she was going through the back door to UNC (or NCSU) — go to a NC community college for two years and transfer.
