If you've received a Knowledgehook Premium class redemption code but want to use your current/previous Gameshow class, all you need to do is upgrade your class! This is very simple, just follow these steps:
1) From the control bar at the top of the page, navigate to the Class Management page.
2) Choose the class you want to upgrade and select the menu for "Upgrade to Premium" and enter your redemption code.
3) Et Voila! You now have a Premium/Missions class with all of your students from before still in the classroom!
4) After assigning a mission from the Missions tab, students can access their assigned work by going to khmath.com and entering the same username and password that they had used in the free class. (Note: If they've forgotten their password, you can reset it from the class dashboard)
