Out of curiosity, may I ask what you decided? Notre Dame was originally my top choice, with Michigan hardly crossing my mind. I loved the size, prestige, and “home” feeling of ND, but was ultimately waitlisted; however, it worked to my advantage, because I actually gave Michigan a chance and loved it when I visited! I was really impressed by the immense opportunities, academic rigor, and most importantly, cost (with financial aid). Either are awesome, so good luck and congrats!
