How to add students to your class:
Go to the "Classes" tab
Click the blue plus sign on the right side of the class to add students
Enter the student's first name and last name
Enter the student's email address into the Username/Email column
When you enter an email address for the username column, students will receive an invitation to join the class once you click the "Add Students" button.
If a student joins your class incorrectly, use this method:
Go to the "Classes" tab
Click on the dropdown menu next to the class name to show the list of students in the class
Click on the bubble next to the student's name
Choose "Remove" from the menu that appears at the bottom of the page:
Then, add the student to your class again. For this, you can either add the student's school email address or add them with a username and generic password which the student can reset.
