Unfortunately, it is not possible to join a class from a teacher account.
However, you can still join another teacher’s classroom by creating your own student account. You can even use the same email address that you use for your teacher account!

If you do join a class as a student, keep in mind that you won’t be able to share the assignments from the class with your own students.
