Is there a quick way to add topics (or weeks) to my course?

Yes, there is. First of all, click on Turn editing on. For adding or removing some topics (or weeks) scroll the main page of your course until the bottom, then click on “+” if you want to add a section or on “-” if you want to delete a section. Notice that always the last topic or week will be deleted.
