I would remove the schools that do not give merit (Cornell etc). Keep in mind that merit is highly competitive at the remaining schools on your list.
What is your school’s history with UNC? Can your parents pay $55,000 per year? There are ways to bring the cost down a little- reducing your living expenses, staying on your parent’s insurance etc.
Take a look at schools such as Pitt, UMD-CP etc. You will likely make honors and possibly get some merit. Rutgers should also be on your list, and you can check out the SUNY schools.
I would sit down and discuss costs with your parents. Congrats on your accomplishments!
