If your course includes access to Personalised Learning, your activation code will enable it.

Add Personalised Learning at the appropriate CEFR level (e.g. Personalised Learning B1) to your class in Cambridge One. For guidance, read: How do I add or change learning materials in a class? 
Please note: Your students will need to join the class and use their activation code to access Personalised Learning. You can share these articles with your students if they need help:

• How do I join a class?

• How do I activate the code for my learning materials on Cambridge One?

You can then assign tasks to them.
