Virtual classes can be used for optimal differentiation.
To create a new virtual class, go to the class list on the Teach page and choose 'Create a new virtual class'. You will see a pop up window where you can enter a name for the virtual class and choose the students you want to put in the virtual class.
Note: Virtual classes created by you will only be visible for you. Other teachers can create their own virtual classes.
You can use virtual classes to differentiate within regular classes. You can differentiate based on level by putting students who are working on different levels in different virtual classes.
You can schedule tests and set goals for virtual classes in the same way as regular classes.
