Congrats on getting accepted into 8 dental schools! That's extremely impressive!
$200k is a large sum of money. Out of the 8 schools you were accepted to, why did you choose Maryland in your top 2?
From what I understand, a decent amount of people from UPenn get accepted into OS; not sure how many from Maryland typically get accepted. I would do the program that has the highest chances of getting accepted into OS. The reason why is the dental program I will be attending had 5 people apply for OS this past cycle, and 0 were accepted. So if there is a program that would increase your likelihood of getting your dream career, I would do it.
