For physics, check the upper level offerings to see that the usual expected courses are offered:
intermediate / advanced mechanics
electromagnetism and optics (often two semesters)
quantum mechanics (often two semesters)
statistical and thermal physics
upper level physics lab
Some physics departments will have additional upper level physics.
It looks like your state schools like UTK and TTU have the basics but not much in the way of electives:

Be sure to run the net price calculator for every college you are considering to see if it may be affordable. (Claims to “meet need” are dependent on the college’s definition of your “need”, so that by itself does not assure that a given college is affordable or not.)
