Chances of being accepted into NC State's School of Engineering (Computer Science major)?

I’m planning on applying to NC State’s School of Engineering this fall to major in computer science, and I was curious about my chances of being admitted since the environment is highly competitive.

My stats:
Unweighted High School GPA: 4.65 (would be higher, but I’m attending an early college where a great portion of my courses are college classes, meaning each A = 4.0 grade points)
Weighted High School GPA: 3.92
College GPA: 4.0
ACT: 28 (planning to retake for a score of 30 or higher)

Virtually all of my high school courses are Honors courses, and I’ve taken a total of 49 credit hours worth of college courses. I’m active in student government; I’m participating in a STEM club; I was my school’s Student of the Year for 2015-2016; throughout my high school career I’ve earned several awards of excellence; I’m enrolled and active in National Honors Society; I have accumulated approximately 250 hours of volunteering service; additionally, I’ve participated in a state-level SkillsUSA Related Technical Math competition and attained second place.

I’m kind of worried about my school’s absence of AP credit, though the college courses likely fostered similar rigor.

Do I have a relatively decent chance of being accepted?

Also, I’ll be applying as an in-state student.

I don’t know much about these kind of stuff, but, how is your unweighted higher than your weighted GPA?
