Congratulations on two great choices. It is essentially what my son had before committing to ND last year, except UW instead of OSU.
What sealed it was when we told him to not worry about the money, just choose based on what he would want without looking at cost. It’s up to your parents to judge their comfort level on cost. Have an honest talk with them. If you can see yourself happy at either place, let them know.
One thing that nearly got him to go to UW was AP credits. He had a bunch, more than a year’s worth, and could have double-majored in three years. Notre Dame gave him 4 credits. It is definitely a four year program. One of those semesters will probably be in Europe.
The major differences:
Cost
Size
Greek vs. Dorms
3 years(?) vs. 4 years
At ND every single kid is super-smart
state vs. private
secular vs. Catholic
The advice seems to be to get an MBA after OSU from a higher rated program.
Get your paperwork in. Tick tick tick …
