What are my chances of getting into NCSSM?

<p>I'm a freshman in CD 1 and I'm planning on applying to NC School of Science and Math next year. I've taken Honors World History, Honors Biology, Career Management Health, and Visual Arts 1 (all A's and highest course averages for school).
I'm currently taking Honors English 1, Honors Algebra 2, PE/Health, and Digital Communications (had no lower than 96 for first grading period of this semester).
Next year, I'm planning on taking Honors Precalc, Honors Civics and Economics, Honors English 2, Honors Chemistry, Honors Physics, Spanish 1 and 2, and Health Science 1.
I got a 160 on my PSAT (1600 on SAT) first time. My GPA is 4.5 weighted, 4.0 unweighted.
I'm in Student Government (Freshman Class Pres. and Homeroom Rep), Marching Band (1st year, 3rd out of 6th chair trumpet), and HOSA (Youngest President in school's history).
I play Rec Baseball (outfield) and planning to play school golf or tennis next year.
I'm very active in my church (choir, usher, and occasional Sunday School teacher) and my community (intern at NASA SEMAA, tutor).
I also do a few summer programs (Labs4Learning at NCSSM, NASA SEMAA, planning to do UNC LEAD in pharmacy).
I also was a Black History Quiz Bowl Team Captain and nominated for awards for Respect and Responsibility.
What are my chances and what are things that I could maybe improve on?</p>
