You seem like a competitive applicant (pending test scores). Lots of the kind of EC’s that UNC likes (some look like you had leadership roles - highlight those). Perhaps a little light on the tougher AP’s (AP Calc, APUSH, AP Bio, AP Chem, AP English Language & Comp). Did I miss - are you a junior? Will you be taking any more AP’s? I think they will like your dedication to health sciences (via your EC’s) and that you want to pursue that career path.
How many students from your HS typically get into UNC each year? You’re essentially competing against the 27 students who rank above you (assuming they also apply to UNC). I think you have some compelling aspects to you resume that make you a competitive applicant but as you may know, being from Wake County (I’m assuming you are) is especially competitive. Make sure you get great LOR’s and nail your essays!
