You have to look at the cds for Michigan.
Common Data Set – Office of Budget and Planning https://share.google/RNA1ZOt6JuTLZl1aU
Go to section C5. The required is 2 year’s for lsa BUT the recommended is 4 years. My son took 3 year’s since he also wanted to take a business course his senior year.
The game is to have over the required amount really for any school you’re applying to.
It’s also not about taking “a lot “of Aps. It’s about taking the “correct “Aps. Rigor is real for Michigan to evaluate.
If you want to share the stats /scores that would be helpful.
