Which License have I?

Hi Ben, 

There are two ways you can access Adobe Express: through a free Adobe Express for K12 Education license that gives access to premium Adobe Express at no cost, or through the paid Adobe Creative Cloud for Education license, which includes Photoshop, Illustrator, and the rest of the Creative Cloud suite of tools. With classroom accounts, individual K12 educators in the US with Google Workspace for Education can create their own Adobe Express for K12 Education accounts and invite students. With district accounts, IT administrators can create and deploy Adobe Express accounts to all students district-wide, using free Adobe Express for Education or paid Adobe Creative Cloud for Education licenses.

Here is another link: https://helpx.adobe.com/in/express/using/express-for-education-students.html which has complete information about the classroom accounts, login to the account, etc. Also, we have got one more link, information about the devices that can access the education accounts, and much more. Hope this will help.

Thanks

Manmeet
