Notre Dame is really really competitive . To get a sense for it, I would check out some of the prior CC threads on Notre Dame acceptances for both early action and regular decision, and see the stats for the rejected students. Each year there are many students with near 4.0 unweighted GPAs, SATs in the 1500s with 100s of hours of volunteer work, legacy status, etc. that get rejected. It is a reach for everyone. You have impressive credentials . . . it’s just not a good idea to have your heart set on a school that is so highly rejective!
I would do what some of the pp’s suggest and identify what you like about ND and find other schools that offer something similar. If it’s D1 football, look at Big 10 or SEC schools. If it’s the Catholic education, check out other Catholic/Jesuit schools. Be sure to have a range of schools you love, in addition to ND!
