And it works?
Well I used them a few years back. All you had to do was 'read' articles and 'watch' videos for a certain length of time, and verify that you were still alive at the end of that lesson by entering your login information. Basically, you could just have it in an inactive browser tab for the duration of the lesson, while you did whatever you wanted, then signed off on the hour when the time was up. Also, you have like a week (or more?) to complete your hours.
