The Viscomm Teacher Resource Package provides a host of valuable time-saving resources for teachers. It can be accessed via Cambridge GO, using the enclosed 16-character access code. The code may be activated once only in one unique teacher account. Downloaded materials may be placed on your school network for use by other teachers at your school and are available through Cambridge GO for a period of 1825 days (5 years) after activation. The Interactive Textbook and Offline Textbook are not included in the Teacher Resource Package.
