What is an eText?
An eText is an online version of your textbook. After you purchase access to the eText, you will be able to open it directly from within the MasteringBiology website. eText access lasts until your subscription to the website expires.
Why buy an eText now?
Your eText is available bundled with MasteringBiology at a reduced cost. (Actual price will be shown before purchase.)
Not sure?
You can always purchase the eText later (at regular price), as an upgrade from within MasteringBiology.
