Umich Transfer chances?

I am a current freshman at Michigan State studying in the James Madison College. For those who don’t know about James Madison, it is a prestigious residential college at MSU that focuses on Poly Sci and Social Policy related materials. At James Madison, GPAs are usually lower than in other MSU college’s because of the rigor so GPAs at James Madison might be lower than usual. I am from Ann Arbor originally, I received a 3.2 GPA in high school and a 29 on the ACT. I want to transfer to Michigan for next year and plan on applying summer semester. With a 3.5 at James Madison in MSU, Dean’s List, my high school stats, and phenomenal extra-curricular activities, what are my chances at gaining acceptance to University of Michigan for this summer and into the fall? Thank you
