Chances for Brown University?

Hi! I’m just finishing up my junior year, I’m an Asian female, and I go to a public high school (though a very large, competitive one) in Texas. Brown is my dream school and I am wondering whether my chances look okay and if not, what I can do to improve them before I apply in the fall. I am looking to major in a business-related field as of right now. My stats are as follows:

Grades:
Freshman year- Biology (A), Geometry (A), English (A), AP Human Geography (A), Health (A), Spanish 3 (A), and Orchestra (A)
Sophomore year- Chemistry (A), AP World History (A), AP Computer Science (A), English (A), AP Spanish 4 (A), Orchestra (A), and Algebra II (A)
Junior Year- AP Physics 1 (A), Pre-Calculus (A), AP Chemistry (A), Orchestra (A), AP English Language (A), AP Spanish 5 (A), and AP US History (A first semester, 89 second semester)
Senior Year- I am taking AP Statistics, AP English Literature, Spanish 6, AP Calculus BC, AP Government, AP Economics, and Orchestra

I have made all A’s except for one B. Is this going to be a huge deterrent? I know people say that grades are never an absolute, but is this something that would completely ruin my chances?

Test Scores:
2210 on SAT, 34 on ACT
AP scores are all 4s and 5s so far

Extracurriculars: I have played violin since I was 5 years old and have been in my school’s varsity orchestra since freshman year and was the secretary of the orchestra this year, I am the secretary of my school’s Science Olympiad team and have been to the state competition two years in a row, I founded my school’s Pen Pal Club, I am part of the Spanish National Honor Society and National Honor Society.

Volunteering: I have approximately 100 hours logged with various service clubs with my school and about 150 hours logged with a local hospital where I volunteered for the past two summers.

Jobs: I have not had a formal job, but I have an internship set up this summer in Switzerland for 6 weeks and an institute which focuses on breast cancer research.

That is essentially it, and I was wondering if I have a realistic chance of getting into Brown. I do have one B on my transcript which right now I think is my biggest downfall. I also don’t know if any of my extracurriculars and things set me apart enough to make me a considerable applicant.

Thank you!

You have a great chance but its still a reach
