This course is estimated to take the student 20 hours to complete. That number is wildly inaccurate. The reading alone took me 20 hours every week. This is mostly due to bad explanations, manufactured student pitfalls, and using concepts not covered yet. In addition to the reading there was Lab videos which had graded questions, Labs with completion grades, Individual assignments with completion grades, weekly quizzes(1 or 2), a mid term, and a final exam.

I have no idea if this course content is useful.

This class is a massive time sink. I had to drop my math class to focus. Be prepared to spend 30-40 hours a week.
