Lots of credits, which college?

You'd have to apply to get your evals, yes, but I would just look into what the schools requirements are on their websites.

Excelsior's Social Sciences major is much less flexible and would probably be quite a bit more expensive than TESC. I don't know if COSC offers a general social science concentration.

If you prefer taking classes to testing out then you could also look into CSU-global. They have a self-paced "independent study" program and offer a social sciences degree. At less than $500 a class (that's per class, not per credit) they're also very reasonably priced. Not as fast as testing out would be, probably, but not everyone is a fan of testing.
