Under the Enrollments heading is the Current Enrollments tab. This tab contains all active enrollments per section. The teacher can also find information about the enrollments in the table configured in the screenshot below. These columns can be customized, if wanted, in the right corner of the page.
Either select a student to edit their enrollment individually or Drop/Complete in bulk. You can also change the Start and End Dates of the enrollment(s) with the Change Dates feature on the screen. Any students who have dropped or completed the Section will be found above in the Enrollment History tab.
When editing a student's enrollment directly, you can update their grades, Assignment count, create comments, and more seen in the second screenshot of this subsection.
