The course, itself, contains 4 hours of video teaching. So if you watch it from start to finish, that’s how long it would take to complete, plus 5-10 minutes per module for quizzes. If you really want to dig in and understand the content, I recommend applying the old college rule: 2 hours of studying for every 1 hour of teaching (12 hours total). If you take full advantage of the bonus content, you could easily add another 5-10 hours (17-22 hours total).
