Are you a teacher using Duolingo for Schools? Your question confuses me.
Yes, you can! You can have multiple class sections.
When your students share their progress with you there is a "section" they can enter. If you request a different section for each class I believe you can filter by section.
I use the teacher dashboard. Can someone guide me on how to do different section per class?How can I have different sections? Is there a customer service number?
