Students who have established a profile can explore videos on their own as long as their teacher has a Platinum Subscription. The teacher just needs to retrieve a code to share with their students, who then enter it when they want to start watching videos.
In the upper right hand corner, go to your Account Settings:
Once in your Account Settings, click on Subscription where you will a Get Class Code button under your subscription information. You must have an active Platinum Plan to create or access a Class Code for your students. Create a label and click on Get Class Code to generate a code that you can then give to your students:
When the students login, they will have an option on the left side of their Dashboard to Unlock Video Access or see a box in the middle of their dashboard to enter the code. Both of these options disappear once students have access.
The student will be prompted to enter the code. After entering the code, they will have access to Videos for as long as you have your subscription.
