The only way a student can be removed from a class is if the teacher removes the student OR if the student manually unenrolls him/herself.
If you are on the classroom.google.com home screen and logged into your account, but don't see your class, please reach out to the teacher via email and ask to be re-invited.
Once invited, visit classroom.google.com while signed in to your cohoes.org account. You will see a "tile" for the invited class. Click Join.Â
