What are my chances for Stanford Business, USC Marshall, and Michigan Ross?

I have a 4.35 weighted/3.7 unweighted GPA
I have a 36 composite act, with 35 english, 35 math, 36 science, 36 reading
I have a vigorous course record with all AP or Honors courses
I have strong ECś including starting a club at my high school, organizing a ted talk in my town, interning for a local representative´s campaign, JV and Varsity volleyball, and I am a member of 4 other clubs in addition to this. Also, I make short films in my spare time, and I have a youtube channel with these short films uploaded.

I am looking to apply preadmit to Michigan and regular for the others in the Fall of 2017.

-Your UW GPA is low for a Standford applicant.
-You have solid ACT score.
-How many APs have you taken? If you have taken more than 12 APs and got that GPA, then it will be fine.
-Good EC

However, I still can’t say you are a solid shot at Stanford as it is one of the most picky schools.
