C21 can be used in a number of ways, depending on whether you prefer printed or digital resources. Both the Course Book and Teacher’s Book have printed and digital versions and the Workbook is available for LMS (we can host it for you if you don’t have your own LMS), or as a printed edition. If you have any questions about what you need please don’t hesitate to get in touch.
