Hiding dash from users- redirect to specific page

Hey guys...

I want membership to just authenticate and take them to a specific page, instead of the dashboard.

I sell tutorials for schools and the school gets a login that all the kids use. How can I best keep users out of the dashboard and just make it so that when they log in, they go to the main page of tutorials they've subscribed for?

I basically just want to have them login for access, but not really have access to any other functions except the unlocked pages.
