Saylor vs. Study.com

[eminor7]

Hello, 

I am new here and I have a few questions. 

1. I would like to know whether Saylor or Study.com would be better for the following courses:

American Government
Principles of Management

2. What is Saylor's PHIL 102: Intro to Critical Thinking and Logic like? Are there a lot of assignments, quizzes? How difficult is it? 

3. What is Study.com's Chemistry 1 with Lab like?

Thank you,
