Mediocre grades and extracurriculars

Hi all!

I’m a junior in high school at the moment and am finding it difficult to gauge where I am in terms of college admissions. Obviously this is on my mind because very very soon I’ll be starting applications.

I have a 3.65 GPA… I have taken the highest classes my freshmen and sophomore year in terms of science and math although I’m still aware this is low. I’m taking AP Calc AB, APUSH, and AP Bio this year and am on track to end the year with all A’s/A-'s, perhaps with one B+.

I don’t have great extracurriculars… starting on the varsity tennis team (on track to be all four years), tennis volunteering (not significant), French honor society, and a business club. My big thing is that I run an online jewelry business that has done over 7,000 in sales, I have worked with local shops and boutiques, and have cumulated over 20k followers on social media from marketing on my own. How much will this one thing set me apart in the college application process? I’m interested in business and entrepreneurship as you can tell. All of my dream schools are reach schools… USC, Babson, Emory… Thanks guys! I would appreciate any tips, suggestions, or thoughts on how I could improve my chances/what my chances are!

Also, I got a 1470 on the SAT. I’ve only taken it once but I’m going to be taking it again, hopefully 1500+ this time, along with the ACT.
