I have the same question, I'd love to watch the presentations in my own time, but I don't want to sign up for something that will have strict deadlines, as my schedule doesn't allow that.

Does anyone know which kind of the two above this course is? I couldn't find that info.

You can find PDFs of the lectures as well as the reading list here:
