Your course was activated in 'My independent learning'

Here are some things you can do:

1. Confirm that you purchased the correct version (e.g. American or British English) and level (e.g. 1, 1A, 2) of your book. Some codes may include access only to the eBook.

For example, Workbook/Activity books Digital Packs can provide:

• Practice Extra or Digital Workbook: these are the online activities that can be assigned as homework when you are in a class

• Student’s Resources: video, audio, etc

If you are not sure what your code includes, go to cambridge.org and check the ISBN number (on the back of your book, under the barcode) to see what is included with your code.

2. Ask your teacher if the class or assignments have the correct materials. They might have picked the wrong level or version.

Activation requires two codes

Some titles require activating two activation codes to get full access to all available materials. Each code gives access to different content:

• The Student’s or Pupil's Book code gives access to the eBook only (a digital version of the book)

• The Workbook or Activity Book code gives access to the Practice Extra (online activities) and Learner Resources on the platform.

Tip: This applies to series like Super Minds, Guess What!, Kid's Box, Be Curious, Interchange, Power Up, etc.

You may have purchased a second-hand book

It's possible that the book you purchased was used or second-hand, and the code was already activated by someone else. 

In this case, we recommend contacting the person, school, or bookstore where you bought the book. You can also fill out this form to contact us with the following information:

• Proof of purchase (receipt)

• A photo of the activation code printed on the book or card

• A photo of the ISBN printed on the book (the number on the back cover, below the barcode that starts with 978)

• A photo of the copyright page, usually found on the second or third page, with a list of ISBNs. It shows where the book was printed (Printed in...)
