Many of our maths and science resources must be activated using an additional reactivation code together with the code in the front of your second-hand textbook. You will need to purchase this code separately to access your digital resources. Learn more here.
The codes in our books may be activated once only in a calendar year and can only be activated a limited number of times. If the code in your book has been activated too many times already, you will not be able to access the digital resources. You can check this using our code checker here.
