Can courses be re-used in second degree?

[SCYankee]

Certainly, a bunch of you folks can answer this question.

Let's say I take the Intro to Marketing CLEP as a pre-req for a Bachelor's in Business Admin. Then, after gaining the degree, I want to earn a second Bachelor's in Communication. If Intro to Marketing is a pre-req for the Communication degree, can it be counted as complete for the second degree also? 

And if it's not a pre-req for the Comm degree, could it be counted as an elective if it was on a list of acceptable electives (or even if any electives were allowed--if there is such an situation)?

Please explain how all of this works. There may be other points I don't even know enough to ask about. So share as much as you like. I'm all ears (or eyes, actually).

Thanks.
