Cheapest but slowest RA school for bachelors

[CarpeDiem8]

I think the time constraints of schools like WGU won't work for me. Let's say I only have about max of 10 hrs a week to devote to classes, no rush on obtaining a degree.

What would you recommend for non-profit RA schools?

ACE - which one (cheapest and slowest) Straighterline, Study.com or something else, like testing out with CLEP? I'm concerned that the CLEP route would mean extra time just researching for CLEP info for each course vs. just learning and working toward goal...

Which BIG 3? is the pacing all the same?

Thanks!
