WGU credits, Study.com and Sophia

[ClockworkHammer]

hi - newbie here...

I'm looking to transfer as many credits as possible to WGU BS Cloud Computing program.

I'm wrapping up all of the IT certs that are transferrable (CompTIA, ITIL, etc.) and then want to move on to Study.com or Sophia. WGU has a nice Partners site that maps their courses to the ones on these sites. Should I start on Sophia to get the first batch (~30) of credits and then move to Study.com for the remaining 20 or so? People on here seem to like Sophia better and it's less expensive. I'm assuming I can bring all three sources of credit into WGU enrollment.

Thanks in advance!
