My student(s) didn't sign up for my classroom

The fastest way to resolve this issue is to ask your student(s) to sign up again for the correct classroom using a different username, but students can reuse their passwords.

Now that your student(s) are familiar with the sign up page, it should take less than 60 seconds per student to complete this task.

And if they all do this simultaneously, your problem will be solved in less than a minute.
