WGU, Straighterline or CLEP for credits?

[studyandpass5]

Hey guys I'd like to knock out a bachelors in business at WGU as quickly as possible. I'd like to know what my best bet is as far as speed and acceptance go. Should I focus on SL? Ive heard some say it takes a month just to complete one class. Also ive read the quality isnt THAT great in comparison to just taking the class through WGU. Or should I focus on CLEP? Study.com? I just want to knock this degree out as quickly as I can, I'm willing and disciplined enough to put in the time/work!

One other question, are there any guides for WGU on this site or others for testing out before enrolling? I did print off the course transfer guide as a reference

I personally prefer a more guided study such as SL or Study.com, but that's my preference. I found CLEP to be a bit daunting in that you only had a vague idea of what was going to be on the test (not to mention the countless study resources that could be used). With SL, there's one book, and everything on the test is from the book. And, a lot of the courses are open book. 
You can try a few CLEPs and try a few SL courses and see which ones you prefer. I know CLEP is free with Modern States, but you have to do what works for you, even if means paying for a monthly subscription, like I've had to do.
