I would focus on the criteria necessary for her to keep her scholarships. At UMD, I know (at least when I was there) that many of the majors like Biology, Computer Science, Mathematics, Engineering, etc gave students bad grades to try and weed out the weaker students. I had plenty of friends that did survive but ended up with a GPA under 3.0. If her scholarship requires her to have a GPA higher than 3.0 and she decides to major in biology than you want to make sure that more than 20% of students actually get Bs in those classes.
It sounds like your daughter didn't get any need-based financial aid. You may want to look into that. I can't imagine that they'd expect people making less than $200k a year to pay full tuition. Make sure to fill out the FAFSA.
Take a look at Yale for example. They charge $64k a year. But what they do is determine how much money parents are expected to pay and then pay everything else. Outside scholarship money goes towards Yales contribution and not towards what you will pay. So, if Yale decides you can only pay $10k per year and your daughter gets $30k in outside scholarships than you're still on the hook for $10k per year. Look, if you're a millionaire or you're making $300k a year than focus on scholarships because you'll be expected to pay a lot of the tuition. But otherwise need-based loans and internal scholarships are probably the way to go.
People have said this already but it's important to look at total cost rather than how much you get. I do suggest looking at total cost some though because scholarships can go away. If prices are equal than it may make more sense to go to Penn State because if things go belly-up you're relying less on aid.
I don't think it matters whether she majors in biology or pre-med. I have a good friend that majored in biology undergrad and then went to medical school. It might be better to major in biology because it gives her more options if she doesn't get into medical school. I have smart friends that struggled to get into med school and it might make sense to leave options open.
I agree that people won't care where she goes to undergrad once she gets her MD. But the med schools will sure care whether she goes to Yale or Elizabethtown.
