Yes, I’m confused by this as well. There’s a program that’s specific to Maine, and includes private colleges? When you say it “isn’t necessarily available everywhere else,” where else is it available?
As another out-of-the-box thought… if you’re interested in a service commitment, would the Coast Guard Academy be something to look at? They have a more normal admissions process, compared to the other service academies. They have both a life sciences major (marine & environmental sciences) and a poli sci major (government). It’s a small college with a liberal arts context, in a gorgeous coastal New England location, and has cross-registration with Conn College (already suggested by another commenter) which is in the same town. And the Coast Guard is very much involved in disaster response/relief. Median weighted GPA at the Academy is 3.79, so, not stratospherically high… and they might really value your strong EC’s. In addition, some applicants, rather than being admitted or denied, are offered a funded preparatory year, after which 85% are admitted. Perhaps not a fit, but seems worth running up the proverbial flagpole. I also agree that Conn College could be a good one to look at, and you could cross-register at the Academy from there if there were specific classes of interest.
