In pset specifications, it is instructed to submit pset through Chrome inside appliance, not any other. Is it compulsory? I mean, can't anyone submit through any other computer? Or any other browser?
I never submitted the psets through the appliance and they got graded fine.
I think the only reason they ask you to do this is because if you haven't configured Dropbox, there's no way to access your VM files from the outside. But once you can exchange files between VM and host freely, there shouldn't be any problem with submitting your work through host.
