Lara,
I believe your question is how to create three topics/sections that are automatically inserted into each course. For example, Section 1 might include instructions on how to use Moodle, Section 2 might include links and instructions for technical support, etc.
There is no way to make this a default for each course. However, you can accomplish this in the following way.
- Create a course that has the three default sections you want to include in all your courses. Give this course a name something like Template.
- In each new course, click "Import" in the Course Settings block. You will be able to select and import your Template.
- The imported Sections (from the Template) will appear in the same Topic/Section numbers in your new course. For example, Section One content from the Template will appear in Section One of the new course.
- If the new course already has other content in the Sections you want to import, drag some blank sections into the slots where your imported content will appear.
