Capella University vs TESU for BSBA Degree?

[BrendaB]

Trying to decide between BSBA degree at TESU or Capella University - Flex Option.   Is there a significant amount of writing involved in the upper level business courses?  Are they easier or harder than using Study.com upper level business courses required for TESU?  Is it possible to finish the last 25% of classes required for BSBA in 12 weeks?
