One thing I've noticed with Coursera is that if you join before the course starts, there's often a preview button that seems to show at least the entire course's video lectures. If the content was useful enough to you, you could take the time to download all the videos and could watch them at any pace, and since you'd always be ahead because of your quicker pace you could still do the quizzes, albeit not straight after watching the lectures.
