Obtaining TWO BSBA's? Marketing and Finance from TESU

[celticlapu]

If I were to get a BSBA in Marketing at TESU (I'm nearly finished and I work at a marketing agency) but would also like to get a second BSBA in Finance. What would that look like? Could I first graduate with a BSBA and then come back and just finish up the requirements for the Finance Degree?   Will I need to retake any classes? I remember seeing discussion in the past stating that You would need to take 24-30 credits for the second degree. Could I use alternative credit sources, like ACE, Study.com etc? Or do they have to be with the school again! 

Sorry for the noob question I was a lurker for many years but lost access to my original account. Thanks for the help!
