My students already have their accounts.
How can I add them to the class? I'm lost as there seems to be no such option.
When you go to your classroom, click on students on the left menu. Then in the top right corner you click the orange invite students button. Then you click share classroom link, and then continue. It will give you a classroom code. Then your students can go to join.duolingo.com and enter the code to join your classroom. I hope this helps!
Thx for your prompt response, but as I've mentioned, they've all created their own, unique DL accounts, have gained some xp points. I wonder if it is possible to invite students in such a case to create a new classroom.
I'm not sure I understand... Even if they have created their own accounts, they can still enter the classroom code and join.
