A class is a group of students using a Cycourse with one or more instructors (usually one). Each Cycourse can support many classes at the same time. Each class sees the same content, and the same exercises.
Instructor can assign one or more users as graders. Graders can use the feedback interface to check students’ submissions, but only submissions from their classes.
Each class has its own page. Students access the page through their control panel. Instructors can add class posts to the page.
Once they have created their accounts, students can ask to join a class. Instructors approve or deny each request. Instructors can drop students from a class, as needed.
