We just saw how as admin or with appropriate permissions, we can add a block to a single course category page. We also saw as we did so that we had the option of adding the block to the courses themselves as well.

When and why might we want to do this? If it is a useful and relevant block for all courses in a category, then adding the block this way will save individual course teachers having to create the block themselves and will also create consistency across the category.

What we've done is set up a category block which will appear everywhere in that category because we have set:

Let us now follow Stuart back into his French course and discover what teachers can do with blocks.
