Do I have a good chance of getting into UNC-CH?

I'm currently a rising senior in a North Carolina public High School, Enloe to be precise. I have a 4.57 weighted GPA, 3.55 unweighted. Through my first 3 years I have taken mostly all honors and AP classes, accumulating 7 APs over the past 2 years and possibly adding 6 more next year. I am ranked in the top 15% of my class of over 550. I play both baseball and soccer for my high school at the varsity level and have received academic all-conference for both. I also play for the CASL soccer league at the classic level. I have been a member of my youth group which focuses on community service and volunteering for 6 years, the last 2 as a committee/board member. Volunteered at a hospital last summer, accumulating between 30-40 hours there. Combining my hours from volunteering through my youth group and the hospital I have around 150 total hours. I have been a NC house of representatives page. Worked for the USA Baseball national training complex. Programmed and maintained a employee scheduling program for a hotel in the state. Work at a hotel as front desk staff, as well as been an assistant for a professional photographer. My SAT score was fairly low but I took it again and have not received my score back yet, I am shooting for about 1900 at least. I received my first C ever in my AP English class this year as a junior. I also have a sibling that is now an alum of the university if that helps. If I achieve above a 1900 on my SAT, maintain my normal A/B grades during senior year, write a good essay which is checked over and edited by multiple teachers, and apply with the UNC-CH early application availability, do I have a fairly strong chance of being accepted into the university?
