Getting into NYU Stern UNDERGRAD

Hi everyone,
I recently finished my sophomore year of high school and I’ve been looking at Stern for quite sometime now. From freshman year until now, I’ve been taking all honors classes and have been doing okay, but not where I would like them. I got mostly B+'s from last year and this year, and my GPA is probably around a 92-93.5. If I were to get my GPA up next year to a 96 (Yes, I know it’s very difficult, but it is possible), and score well on my SATs, where would I stand? As for my extracurriculars, and hobbies as of right now:

-I play trumpet (from 3rd grade until now) I will most likely make the All-State band in the upcoming year
-Member of the school’s jazz ensemble (2 years)
-Member of DECA (2 years) I placed 4th at the New York state competition in entrepreneurship, which allowed me to attend the international competition in Nashville
-Member of an outside concert band (2 years)
-Member of the speech and debate team (1 year) I’m getting more serious with that and plan to attend more competitions and invitationals
-I have my own clothing brand
-I plan to start a new business club next year
-I am joining a world languages club next year, as well

For a career, I would either want to pursue a career in the fashion industry, or finance.

For this summer, I recently got accepted into a program hosted by the New York Times called “The Price of Everything: Steering the Global Economic Engine,” which is taught by Eduardo Porter, who writes the Economic Scene column for the New York Times. Every student attending gets his or her own recommendation letter, which I believe would help my chances considering I have a good understanding of finance and believe I can get on the instructor’s good side, lol. If you could please give me some tips and pieces of advice on how to increase my chances, I’d greatly appreciate it, thank you!

P.S. I plan on making the most of my junior year academically (getting straight A+s, good SAT score, good AP scores, and good scores on a few SAT subject tests), in terms of my extracurriculars (finalist at the international competition in DECA, doing well in my speech and debate club, and making the All-State band for trumpet), and my own interests (pursuing my clothing brand, etc.)
