One course in two of these sciences is not the same as taking all three plus an AP course in one, which would be typical at the schools you mention. As would at least three years of a foreign language, though a lack of offering at your school may provide some relief from that expectation. Another of those three science classEs, rather than EMT, Journalism, or Sports Med could be of significant benefit.
And I can assure you that these schools, and all others, absolutely pay attention to your Senior year course selections.
