Is it possible to import a roster from Excel so I don't have to type each student's name?
Instead of importing a roster, why not have the students join your class using: Settings; Progress Sharing; Email; Join class function. I do not enter my students' names. I have them add themselves by using the Invite feature.
Personally, I don't want to have to chase down my kids when they don't do it. If I have a list, it would be easiest for me to just import it and be done.
