When you choose a plan, you're signing up for a 4month 'term'. You can opt to make a onetime payment for the initial 4month term or pay monthly. If you opt for monthly payments, we will charge your payment method each month until your 4month term has ended. You can turn on autorenew in My account at any time to continue your subscription before your 4month term has ended.
When you purchase a Pearson+ subscription, it will last 4 months. Before your initial 4month term ends, you can extend your subscription by turning autorenew on in My account.
If you turn autorenew on, we’ll automatically renew your subscription and charge you every month until you turn off autorenew. If you made a onetime payment for your initial 4month term, you’ll now pay monthly.
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 autorenew has been turned off by purchasing another Pearson+ subscription. We use your credit card to renew your subscription automatically. To make sure your learning is uninterrupted, please check your card details before your first monthly payment.
