When you are in the teacher panel of a loop that you have started, you have the opportunity to switch between different settings to get a good overview over your students’ work. Click the headline Students and you will see a list of the participants in the loop and a progress bar for each student. The list will give you an overview of the work in the group and how far each student has come. (You can choose to hide or show the exact number of tasks submitted by each student by clicking the crossed out eye). Switch to Assignments to see all the nodes in the correct order. Watch the progress bar for the tasks and you will get a good sense of how far the group has come with their work in the loop.
