Make the most of your study time with offline access, enhanced search, notes and flashcards — to get organized, get the work done quicker and get results. Plus, with the app, put textbooks in your pocket and learn wherever. It's time to upgrade the textbook and simplify learning, so you can have time to live too.

Pearson eText is an easy-to-use digital textbook available from Pearson+. Make it your own by adding notes and highlights. Download the Pearson+ mobile app to learn on the go, even offline. Listen on the go with our new audiobook feature, available for most titles.

When you choose a plan, you're signing up for a 4-month term. We will charge your payment method each month until your 4-month term has ended. After that, we'll automatically renew your subscription and charge you on a month-to-month basis unless you turn off auto-renewal in My account.

When you purchase a Pearson+ subscription, it will last a minimum of 4 months, and then automatically renew each month thereafter unless you turn off auto-renew in My account.

If you want to stop your subscription at the end of your 4-month term, simply turn off auto-renew from My account. To avoid the next payment charge, make sure you turn auto renewal off 1 day before the auto renewal date.

You can subscribe again after auto-renew has been turned off by purchasing another Pearson+ subscription.
