No. When you buy an access code for the student's book, you also get access to the workbook.

When you add a book to your content on the platform, it includes the resources in both the student book and the workbook. If you have access to the digital book, you will find the digital workbook after the student book. You can click on the icon on the far left of the toolbar to display the table of contents and go directly to the exercise book.
