You can access AV4 online at https://av.santillana.es/. You will need to: 

1. Create an account, using the book license and password provided by your commercial delegate. 

1. If you are a teacher and already registered for e-vocación, you can log in with the same credentials (DNI + password). Once inside the platform, you should see the same books available as on e-vocación. 

If you need to access content offline, you can download the Aula Virtual 4 Offline application from https://santillana.es/descargas-aula-virtual l or through digital stores: Play Store (Android) / Apple Store (iOS, MacOS) / Download Server (Linux – Abalinex, LinEx, EducAndOS –, Windows, ChromeOS). 

In both cases, whether using the online platform or the AV4 Offline application, you must log in at least once to the online platform after creating your account.
