We will be permanently retiring all disc products and ending sales no later than October 31, 2024…

and some of our inventory may be gone even before that date. In other words, we will only be selling discs through October 31, while supplies last.

For information about using the discs with a Mac, click here.

We will also stop providing support for installing, activating, and using the discs on January 1, 2026.

Individual replacement discs can be ordered until October 31, 2024 or until they sell out, by calling our office at (405) 525‑3600, M‑F, 8am‑5pm CT.

Printed textbooks* with answer keys will still be available after the discs are retired.

*Our original, spiral bound textbooks are being replaced with lay-flat bindings with perforated pages. We apologize, but we are not able to accommodate specific binding requests.
