To change a student's Class section, start by going to the "My class" tab in your class zyBook.
Click on "Manage" and scroll down to the card labeled "Manage students". Select a student from the drop-down menu and the option to assign the student to a section will appear.
If you have questions regarding why a zyBook might need to use class sections, please refer to our other help article on "How do class sections work?".
