Question About 24cr Rule for 2nd TESU Bachelors

[csbachelor]

I wanted to confirm whether there are any restrictions on the source of credits for the 24cr minimum required for a second TESU bachelors degree. 

I already have a BACS from TESU and am looking into getting a Math BA as well. I need 24 credits, but can they come from anywhere? Are study.com or Coopersmith credits accepted or do they need to be from a regionally accredited institution? Thanks
