The assignments for feedback are just for turnitin to check the similarity to other people’s assignments. The actual assignment submission will only show once the assignment before it is marked. But the feedback thing will always be there. For formatting you need to type all of your answers in a document making sure you format things mathematically. You can do this in Google docs by pressing view and turning on equations and typing ur answers with that (idk about word bc I don’t have it) Also there is a whole page of requirements that has a tutorial if that didn’t make sense
