So you are way early. My suggestion - have mom / dad take you to some nearby schools - I don’t care the rank etc. go see some urban like BU and northeastern , rural like UMass. a Brandeis, Clark, Wheaton, Connecticut, URI, UNH. See a mix of urban, suburban, rural, large, medium and small.
One great thing you’ve noticed is that college is pricey - I need merit.
So I think you have lots of time to form a list but you seem to only have large except WUSTL. Are you sure that’s what you want ?
Given your career path, the where won’t matter. But you’ll have 8 years of cost.
So your parents will have to give you a budget. A U of Alabama, with its McCullough Medical Scholars, will be $20k a year. Others like UNH and URI more but Michigan / UVA / UCI $80k plus a year by then.
So if you have a tight budget, the where you apply matters. And the med schools won’t care where you went. But your ability to pay for med school will be impacted.
Now you have Michigan and WUSTL. These schools and others on your list are different in so many ways.
So no need to panic AT ALL. It’s a great topic and you have lots of time. But over the next months, on weekends, have your folks take you to a school or two within driving range.
You might find UMASS too big and Brandeis the perfect size.
You might find you like the more suburban/urban feel of Unc vs the urbanness of BU.
Your time now should be set in exploration and during the next summer, working with your family on a budget - an eight, not four year.
Then you have plenty of time to do visits and build a proper list next year. I am guessing that while your list is fine, it’s not attuned to your finances or other needs.
Good luck.
