As far as Michigan goes it’s tough for everyone. My son went to the #1 high school in the state the year he went. Selective enrollment school. If your school is NT then it’s a feeder school. That is what you want to find out. How many got accepted and with what scores.
As far as cost, your educated to make that decision. Don’t listen to the noise. We chose the extra expense and it was worth every penny.
Write a great essay. It counts. Go to sessions. Go on the websites and check out the schools. It all counts.
But I always say be careful what you wish for. It’s a very hard school especially their math department.
Good luck. AP Calc is fine. Does she have a chance to go to a higher math class instead of Stats? If your school offers something higher this can come into play in their decisions.
