Your profile is, in a lot of ways, almost exactly the same as mine was before I was accepted (into CSOM). Your weighted GPA is within .05 of mine on the 100 scale. Your SAT is 10 higher on a 2400 scale. Our ACT is the same, despite the fact idk your sub scores. And I also took 3 SAT II’s, averaging around the same as well (650, 750, 770 for me) if I remember correctly. I also had a spot in FBLA, took 3 AP’s by junior year, and took 5 more senior year. I was also a white applicant from the northeast and, from what I can tell, the breadth of our extra curriculars, while different, would probably be equally strong in the eyes of an admissions officer (I’d assume). If you care to compare any further, check my past chance me’s from before I got in. You can find them in my post history.
With that said, you have a great chance. I know we’re not exactly the same person or anything, and essays are obviously a factor, but you should have a good shot. I was given 4 years of housing, which is apparently offered to the top 10/15% of the class, after all the nurses, athletes, handicapped students, etc are provided housing. The reason I bring that up is, if our applications are viewed as similarly as I think they would be, there’s no reason to think that you wouldn’t be at least accepted or even given the 4 year housing option.
You say you applied for Econ. That can mean either CAS Econ (BA) or CSOM Econ (BS). I applied CSOM Econ and supposedly CSOM admissions criteria are a bit more stringent, so you definitely have a good chance both ways, but maybe a bit better if you did CAS.
Hope this helped. PM me if you have any questions
