Cambridge One classes are designed for a limited number of activities. Whenever adding materials to a class, it is not possible to add a material that, as a result, exceeds this limit.

If you create classes in bulk, you will find one of the following messages:

• ‘Please select Adult segment’

• ‘Please select Primary segment’

• ‘Please select Secondary segment’

We recommend limiting the amount of titles added to a class whenever possible. If your student's use multiple Cambridge titles for their classes, and you receive this message, you can create separate classes for the titles your students use.
