First Sophia credit, academic level? how in compare other courses

"Congratulations, you've successfully completed all course requirements.
It may take up to 2 business days to finalize your course and prepare your official transcript."

Yeah, that feels good! My first (USA) credit, at a Sophia free course.

But this is open book, im wondering what these free courses at Sophia compares with other courses.
Are the other courses more difficult? Are the free courses easy in compare with others?

Is it harder to complete the other courses on academic level? ( at the universitys, study.com etc) And to be honest, is Sophia open book academic level?

Love to read all about it!
