What are my chances? Ivies, etc.

I just wanted to post this to get some feedback as to what people think my Harvard REA decision might be (I AM SO NERVOUS AND IMPATIENT). I am also applying to Yale, Columbia, Brown, and Penn, as well as Northwestern, WUSTL, Hopkins, and Tufts (along with safeties, of course), so if anyone has any insight on which of these schools I have a shot at, I would appreciate the feedback.

Background:
•white female
•first generation college student/grad (my mom completed some community college)

My School
•an “ok” suburban public school- (Niche report card: B overall, B+ academics, B+ teachers, C+ clubs, B- college prep, C+ resources)
•last year’s valedictorian attends Harvard (idk if this matters at all??- just thought I’d throw it out there)

ACT Score:
•highest single test: 33
•“superscore”: 34

AP’s:
9th Grade:
•Human Geography- 5

10th:
•US Gov- 4

•Scholar Athlete (10th-11th)
•Principal’s Honor Roll (every year)
•AP Scholar (10th), with distinction (11th)

Overall, I think I have an okay chance, but I know it’s a crapshoot and my test scores are not as great as they could be. I think my essays were solid (I have received great feedback from my GC and english teacher) and my Harvard interview seemed good, but not too exceptional.
