Help me choose undergrad business school...

GPA: 3.78, ACT: 35 single, 36 super, Applied to finance at every school, No class ranking, and I go to a presitigous #2 private high school in the country, Bulgarian.

EC's/Activities (Ultra Shortened): Story writer for an award-winning business publication at my school, head of a summer research team at UTD that discovered practical commercial use of supercapacitors, TA and ex-student at Awesome Math, CFO of a non-profit that brings financial literacy education to underprivileged schools in my area, TA for a Level 3 proficiency summer Chinese course for young students, Gendercide Awareness Project member and gave presentations to a local all-girls school, Leader in a society at my school where we meet with younger students to mentor them about the high school experience.

EA: Notre Dame (REA, Rejected), UVA, Georgia Tech, Fordham (Accepted), SMU (Deferred), Indiana University (Accepted, Kelley), Purdue, Georgia (Deferred), UCLA, UC Berkeley, UCSB

RD: NYU (ED2), Brown, U Penn, Michigan, Boston College, USC, Villanova, WashU, University of Texas, Texas A&M

I feel like I've got my application strategy down, but my Notre Dame (dream school) rejection and SMU deferral seriously bruised my ego and have made me uneasy about college apps. I decided that NYU Stern was a good ED2 considering my stats and EC business background, and since I am in the green for my school's historically good NYU ED acceptance rate. I also feel pretty good since I am relatively top-right for applications. 

I've been seriously considering IU Kelley b/c it's my worst-case-scenario school from here on out. Hopefully, I get into some more. Any tips, advice, experience at any of these, chanceme's? Also, goal is IB.
