Hi there. For both of these courses the lectures are online, so you can just watch them when you have time. There is a courseware for you to make notes on, and it contains all of the lecture slides.
Tutorials are where you discuss the material and see if you really understand it. There are weekly (?) quizzes with about six or so questions. I found that XX3 was a bit easier than X03, but it probably differs from person to person. If you want to know any more just ask
