Straighterline -- and vs. Study.com?

[aviator guy]

my opinion only...
I feel like Study.com would be better if you don't know the materials. Straighterline would be for stuff you already have some knowledge/experience in. That's just me.
Study is straightforward and bite sized and steady paced. Much easier digested and tested on an unknown topic.
Straighterline has two textbooks, and one is just an E book version of the big college course textbooks you'd buy for a brick and mortar classroom. Way too much stuff to cover to make it worthwhile to take if time and cost are important to you! (I really can't explain it well, but I'm trying!)

I think I get what you're saying.  Study.com's content is more streamlined?

Straighterline's MO is pretty much "here's some stuff, take the tests."

Study.com does a much better job of "drilling" the material and you retain it a bit better. They cut everything into small chunks, then you practice with a 5 question quiz for that "chunk."

With Straighterline, I have typically done worse than I expected on finals, even with subjects I know fairly well. With Study.com I have done better than anticipated on the finals, even with material I didn't think I knew that well.
