To join a Class from a Tinkercad account:
Log into www.tinkercad.com with your Tinkercad credentials or “Sign in with Google” and your school email.
In your Dashboard, click “Join a class”, or click the Class link your teacher gave you.
If not joining by the Class link, enter the Class Code, then click “That's me!”.
The student will remain in the teacher’s Class, and there is no need to rejoin the Class with each login. Students joining a Class from their account will log back in normally and remain in the Class until their teacher removes or deletes them.
