Good Morning,

Typically, these files would be provided to you with the book that you purchased. Usually either by CD or a link to retrieve them online. If you do not see this in your book, I would suggest reaching out to the publisher and letting them know so that they can replace them for you.

Please do not hesitate to let us know if you are not able to reach the publisher and we can see what we can do.

Regards,
Sage Education
