If you've received a Knowledgehook Premium class redemption code and want to upgrade an existing class just follow these steps:

From the control bar at the top of the page, Click on the Knowledgehook logo  to navigate to the class page 

Choose the class you want to upgrade and select "Premium " to downgrade from the "free Premium".

Then Click "upgrade" and input your premium code .

Nothing changes for how students login, they still go the joinkh.com and enter their class code.
