Some of our titles come with a key, what does this mean?
For some of our titles, there are two versions of the book: With key and Without key.
The ‘With key’ version means that the book comes the answers, which is suited for independent study. The ‘Without key’ version means that the book does not include the answers, which is suited to students learning in a classroom setting.
Please ensure that you are selecting the correct version when you are purchasing the title, as if you have purchased the version without the key, we are not able to provide the answer key due to copyright protection reasons.
