RA credits self paced online like Sophia platform?

[ss20ts]

I have checked around this site. Many recommendations indeed but I know it all depends on each learner. Could anyone suggest the easy math and science RA college credits that could generate a transcript for cheap that can be completed at your own pace/competency based 100% online? I just can’t handle a long semester. Perhaps earning one 12 credits quicker? 
ASU just seems a lot for me. I try to avoid as much RPNow due to the long delays.

You might look into the BYU and U if Idaho. They have self paced courses. I want to say they're around $600 a course.
