Reminder: Not all instructors or courses will use Moodle. Accounts are only created for users who have at least one course using Moodle. Updates to Moodle enrollment are typically processed 1 business day after the student registration activity.
Students will only see course sites that have been activated by the instructor, typically on the first day of the semester. If you log in before any of your specific course sites are made available, you will see the course catalog of all "Available Courses" instead of just your individual "My Courses" listing.
