Can Someone Explain FEMA Classes

[empowered2teach]

Hi All! I'm new to CLEP tests, but I've recently passed the US Government and planning to take the US History this February. I've got a question, though about FEMA. I've noticed that many on this list have taken the courses. Would someone explain when one should seek out these courses? Are they just fillers for extra credit towards graduation? Or are they degree specific (and applicable) classes only? Thanks in advance!

So far towards BA in Liberal Arts:
40 traditional creds
1 CLEP (American Gov't)
