Go to this page (it will open in a new window). Here you will find the contents of the course in the middle column. You have to go through everything from top to bottom, because activities in this course are conditional.

Please take care that you finish and submit any quiz you have started, like the introduction quiz, so that you can proceed to the next activity.
