Textbooks with companion websites are now available. Students may join their teachers’ courses and will be able to enter their access code or purchase access at any point in the 14-day grace period that begins on the first date of access.

How do I join my class on the companion website for the first time?

If you are learning without a teacher, please see the instructions on the Independent Learners page.

If you are learning with a teacher, follow the instructions below:

If you have received a Course Link from your teacher, click the link and log in or sign up for a new account. You can purchase access to the companion website when you create an account or before the 14-day grace period ends. You are now connected to your teacher’s course!

If you have received an email from Lingco (the website platform) notifying you that you have been added to your class’ roster, click on the link in the email, then log in or sign up for a new account. You can purchase access to the companion website when you create an account or before the 14-day grace period ends. You are now connected to your teacher’s course!

If your teacher has given you a Course Code, click here to create an account or log in to the companion website platform, Lingco. After you have logged in or created a Lingco account, you will be prompted to enter the Course Code provided by your instructor to join their course. If you do not have a Course Code yet, you can link to the course later by logging into your account and inputting the Course Code at any time. You can purchase access to the companion website when you create an account or before the 14-day grace period ends. You are now connected to your teacher’s course!

If you bought a textbook that does not include an access code, you can purchase access to the companion websites separately on the publisher’s website. See the Product Guide for more information.
