Are you planning to take physics and a third year of language in senior year? I think these will strengthen your course rigor and therefore your overall application.
You are not a resident for Michigan. That usually goes to where you will graduate high school. I grew up outside Detroit and it didn’t feel right that my son went to Michigan as an out of state student since we haven’t lived there in year’s. Lol.
As great as a student as you are don’t let up. Take the most rigorous senior classes as suggested. Look at Michigan’s requirements and meet or exceed them. Many applying will. ED as you know is new this year. They haven’t figured how many students they are targeting yet. They only use unweighted scores.
How many students applied and how many got acceptances to Michigan in the past from your high school ? How many actually committed and went? Some of this matters do a degree.
Not a bad thing. But some students like following procedures to get answers rather than proving things and don’t realize that math is mainly the latter until later.
