To remove a student from your class section, simply click the "Manage Students" tab on the left-hand navigation bar and find your student's name.  Move your cursor to far right-hand side of the screen.  Hover over the gray X, and click it.  From there you can choose to remove the student.


If the "Manage Students" tab is missing, this means you have synced your GrammarFlip account with your Google Classroom.  To remove a student, you would simply remove that student from your Google Classroom first, and then you would click the "Sync with Classroom" button on your GrammarFlip teacher dashboard.
