Cheap, Easy, Fast Degree - Help Please

[Zee28]

So I went through the links but now I'm even more confused... why do some people take courses from different schools?for example someone was doing their degree with charter oaks but took a couple courses with Penn foster.
Also why chose to go through study.com for example if the course has a 100 quizzes and several exams?
Also I read in one of the links that TESU allows up to 90 credits but has too be from a single source. Does that mean we can only use Sophia.com for example?
Another question is I read charter oaks let's you test out on like 90 percent of the business administration degree is that true? Also what do u guys know about charter oaks in compared to TESU?
Also how can I find out for example which school has the least writing? And which one has only multiple choice exams or mostly? So basically like which one is the easiest?

Thank you in advance!
