In-state; Early Action; H.S. Class of 2018; What are my chances?

Greetings! I’m currently a Junior in High School hoping to apply to UNC-CH this summer for Early Decision. I am an in-state legacy, although I’m fairly positive being a legacy doesn’t help for UNC-CH. Here are my stats!

ACT: 34
School Type: Public
Unweighted GPA: 4.00
Weighted GPA: 4.90 (6.00 Scale)
Class Rank: Top 5%
Ethnicity, Gender: White Male

I have taken three AP Courses and two AP-Weighted Engineering Courses:
AP Calculus AB – A, 5
AP Music Theory – A, 3
AP Chemistry – A, 4
PLTW Introduction to Engineering – A
PLTW Principles of Engineering – A

Most of my courses otherwise have been Honors, unless unavailable.

Extracurriculars:
Stage Manager, Theatre Program
Bass in Drumline, Marching Band
Officer for Mu Alpha Theta, Mathematics Honors Society
Captain of Chemistry, Science Olympiad
Member of NHS; National Beta Club; Music Honors Society; International Thespian Society
150+ Volunteer Hours

What are my chances?

It should be noted that my first-semester, Senior Year courseload should be as follows:

AP Statistics
Community College Calculus II
Programming I Honors
Band I

I think you will get in with your score since you’re in-state. Good GPA and extra-curriculars.
