On Quill, each classroom has a unique class code. Students can join their teachers' classes and access their assignments by entering the class code when prompted upon login. Students only have to enter the class code once to join a class.
To Access the class code, go to the Home tab and scroll down to the "My Classes" section. The class code is located under the class name.
This class code does not change and can be used in the future to add new students to a class.
