Why is IU better having been to both multiple times - they are different. Not sure one is better but that’s up to you.
In the end, it’s your gpa, mcat and other factors that will matter vs the where.
The other thing - you have no budget but think 8 years, not four. Another $400k. Will it matter Vs full pay at Cornell etc which will be another near $400k. Something to think about b4 you ED.
