Choose a category and subcategory for your course from the Category and Subcategory pop-up menus, then click Save.
You assign categories to your courses to help students search and browse content in the iTunes U catalog. While multiple categories can apply to your content, select the most relevant category. If no subcategories apply to your course, do not select a subcategory.
