I don’t think it’s surprising at all. The top students from Classical tend to do very well in highly-selective admissions. Urban exam and magnet schools are a source for FGLI and economically diverse students who are seen as reasonably well-prepared for demanding college-level academics.
You have a lot going for you, especially with respect to community leadership and impact, which is something Penn values a lot. Shoot your shot.
Follow the advice you are getting in this thread, however, and make sure you have a balanced list of schools. Don’t put a target or likely school on your list just to have some more predictable acceptances. Have schools you could really see yourself attending.
Also, understand the trade-offs in your criteria. You have two that are producing some conflict: the desire to major in a strong international business program, and an affinity for the northeast. Holding fast to one limits the other.
Good luck.
