Yes. If you purchase a licence and pay the full amount in one transaction, you can renew your licence at the end of 12 months by re-registering.
To do this, click on the register button on the relevant programme page and log in as an existing user using the hyperlink at the bottom of the page. Proceed through the registration process as normal. You can then continue to access your existing account and previous learning history.
If you have purchased a licence and pay by monthly subscription then your payments continue automatically and you do not need to re-register.
