Provider:  Study.com
Course:  Business 101: Principles of Management
Course content:  16 Chapters with 119 lessons (video and text), and 119 5 question quizzes.  Quiz score determines passing score for final (minimum final grade is 55% assuming all quizzes are 100% but you only get 3(?) attempts per quiz to get the max score on the quiz.)  Each chapter has a practice test and a 50 question practice final is available.  
Final exam format: 100 multiple choice questions.
Final exam content vs course content/practice exams: It was probably 25% new material that had been presented in the lessons but not drilled.
Time taken on course:  Approximately 8 hours.
Familiarity with subject before course: There was some overlap from other courses, a lot of common sense stuff.  I probably would have scored 50% on the final with no practice.
Pitfalls, high points, things others should know:  You can take placement tests to work through many of the lessons (meaning you don't have to take the quiz for the lesson) and this greatly increases productivity.  Between this and having some carry over (some topics were covered in other courses I had worked on) I probably eliminated 50% of the content right off the bat.  A lot of questions on all of the tests can be whittled down through common test taking methods - context clues, process of elimination, etc.  Pro tip:  Study.com loves them some philosophers and theorists - knowing all of the names and theories in the course is an easy, low effort grade booster for the final.  Should you retain this information it will also allow you to name drop and exert your intellectual dominance in petty arguments for years to come.
1-10 Difficulty level: 3

Every time I come on these boards, I feel slightly inferior (lol), only because I'm currently taking this course, and I'm certain I've spent at least 20 hours on it and I'm currently doing the Final Practice Exam (you can take this at least 8 times if you like - I know I did it on another Study.com course). The videos are 119, averaging 8 minutes each. The quiz after each video takes about 2 to 3 minutes, there's flashcards that took me 1 hour to review, and I plan on taking a good 6 practice exams (3 hours): 16 hours videos, 4 hours quizzes, 4 hours flashcards + practice exams = 24 hours.   Still, the content is like a 3, as you said.  If you don't have old eyes, you can get through this in a very focused weekend session.
