Chances into University of Michigan?

Hey guys, I’m currently a sophomore in high school. I know it’s a bit early to ask, but I’ve been thinking about colleges and it’s so nerve-racking.
My question is: Do I still have a good chance of getting accepted to University of Michigan if I have a high GPA, but a low ACT score? Not to mention, I am also enrolling into the IB program. My main concern is the ACT score…

I also had another question, is it true that it’s easier to get accepted if you’re in state? I live in Michigan and from what I read on the internet, some people have said it’s harder if you’re out of state and applying to U of M.

I hope you guys can answer, it would mean a lot! Thank you!
