The Registration tab allows you to enroll in courses. Choose a semester and select courses from the list. Clicking on the green + sign under Enroll puts you into the course. If a grey lock icon appears instead, the course has a prerequisite that you haven’t fulfilled. Clicking on the course number and title gives you more information about the course. After you’ve enrolled in courses, be sure to click the Save button.
