All courses will look relatively the same, making the course structure fairly uniform across all sites unless you opt to use a tool like DesignPLUS to add additional styling. You can also customize your home page to be one of the following:

• Course Activity Stream (most recent activity and interactions).
• Pages Front Page (select a page in the course site to be the site's landing page).
• Course Modules, Assignments List, or Syllabus.
