Credit for Spanish: CLEP vs Straighterline vs Saylor vs AP

[jplot002]

Hola a todos.

Here's my situation:
I took AP Spanish and AP Spanish Literature in high school. I have those credits on my transcripts. I also took Spanish 280 and Spanish 285 at my community college, and got C's in those. I was tuned out and bored since I spoke it well and didn't do homework and blah blah blah.

Now I'm looking at options to retake these tests, and replace those C's with the P from these courses. 

My guess is that all of these courses would be roughly equivalent in terms of the knowledge required to pass them. I'm honestly kind of surprised that they took my 280 and 285 after AP SPanish literature. IN all honesty, that high school lit class was a lot harder than the college classes.

Does anyone have any experience they can comment with? 

Or even crazier, is it possible to get credit from multiple testing places? Why not go all in on Spanish if they'll let me.
