If you look at the UNC-CH Common Data Set, under Part C7 it states that standardized test scores, application essay(s), letter(s) of recommendation, and the rigor of your high school record are “very important” academic factors considered for freshman admission, whereas GPA and class rank are “important” academic factors considered for freshman admission. Extracurricular activities, talent, and character/personal qualities are considered as “very important” non-academic factors.
Further, Part C9 of the Common Data Set for UNC-CH, gives you the median 50% for both SAT and ACT scores, as well as the percentage of the entering first-year class falling within certain ranges of SAT and ACT scores; and Part C11 gives you the percentage of entering first-year students falling within a range of unweighted GPA on a 4.0 scale.
By way of comparison, our OOS high school usually has 8-10 students who apply, and 1-2 students who are admitted, each year to UNC-CH; and, with the exception of legacy students, our admitted students have ACT scores of 34+ and weighted GPAs of 4.5+. These successful applicants also were involved in extracurricular activities that showed commitment over time (no “drive-by” ECs), and demonstrated leadership in the school as well as their ECs. Other kids in our city who I know were admitted to UNC-CH recently also had similar academic statistics and non-academic characteristics; and all of these kids were “unhooked” in admissions parlance (i.e., not a recruited D-1 athlete, or a URM, first-generation college student, etc.).
Your GPA is fine; the problem I see is with your SAT score. According to SAT/ACT concordance tables, your 1340 SAT score converts to a 28 ACT. If you are a URM (“under-represented minority”), recruited D-1 athlete, first-generation college student, or OOS legacy, you may be able to get around the low SAT score. Otherwise, I agree with @kjake2000 that your SAT score is probably going to be too low for you to be competitive for admission as an OOS applicant; so to the extent that you can, try to boost your standardized test scores.
Also, the things you have listed under “leadership” seem to be a bit lacking in heft; and your ECs don’t seem to show much in the way of passion or commitment over time. That may be a function of how you have presented them, however.
