For Desktop - if you don’t know how to find the link to the Shaivite University from the home page - see this screenshot. Click on offerings.
Then open Shaivite University link - like shown here.
You can’t see the menu or other resources in the Shaivite University until you login. So this is where you start.
In some cases you will see the menu - but would not be able to go to the page like this.
After Login
