Yes! Students can be registered in multiple classes without having to create more than one account.
After the student has created and signed into their CommonLit account, they should go to their “My Account and Classes” page. Make sure that the student has the code for their new class.
Under their “My CommonLit Classes” section, they should see a “Add another class code” link. Have the student click the link and enter the new class code to register in an additional class.
