Some of the comments below regard the MOOC, offered on the edX platform, based on these materials.
The beauty of an online course is that you get to study when you want, where you want. Still, deadlines tend to keep people moving forward. There are no intermediate due dates but only work that is completed by the closing of the course will count towards the optional Verified Certificate. Even when the course is not officially in session, you will be able to use the notes to learn.
