In every loop an Assignment list is created for you as a student. It contains the work you need to do in the loop. You can go to the different nodes straight from the list to work with them and submit the answers. When a node is completed a small green check symbol will appear on it. On the pink and yellow nodes the check symbol will appear immediately after you have indicated that you’ve finished the work in the node, since no answer is required in those nodes. In the blue, green and purple nodes, the teacher gives the student the check symbol by approving their work. You will also get pink notification dots, both in the list and on the map, if the teacher or a classmate has written a comment to you.
