Agree with above about contacting schools where you are waitlisted. I would also emphasize keeping it to the point and BEING POSITIVE. Let the school know why you believe you would be a great fit and could succeed and contribute to the community. This is very important, in this case and always.
That message is what would help an admissions committee decide to pull you off the waitlist, not that you got a raw deal in high school.
If that does not work out, embrace UNC-A or UNC-W or another school where you are accepted. I promise that you will meet very many amazing people at any of these schools. It’s HOW you go to school, not WHERE. You control your future much more than the school name on your degree. Work hard, be positive, treat people well and you will do well. Good luck!
