Creating a classroom is as same as creating a department on the web app. For that, first, go to create > classrooms.
Enter the details such as Title, Description, then select the department. Click on the Create button to construct a classroom.
In the mobile app, to create a classroom,
Go to the classrooms (on the front page of the dashboard) > New > Enter details > Create.
In a classroom, we can see the summary and description on the top left side. The bottom side of the classroom square provided the invitation link to students to join the class.
