When you create a new billing account for you and other teachers to use it is set into an unverified state. Even unverified though you can still do pretty much everything you want to use ClassCube for. You’ll be able to create problems, share them with your students, and have students share their solutions with you.
The only difference between an unverified and verified billing account is which of our problems you have access to. In addition to the free problems that everyone can attempt and create assignments from, verified accounts also have access to an additional set of problems that you can use to create assignments for your students. We decided to keep a manual verification step between users and these problems to limit who has access and try to keep students from setting up dummy billing accounts to try and get access to the additional problems.
