Hi there, I'm having an issues with submitting my quizzes. The message "Error: invalid response from server" pops up. I've tried from a couple of different devices but the same issue occurs. It worked once (for Module 4 - lesson 1) but has failed since going back for Module 1 quizzes. I was wondering if you knew why this is happening?

Hi all, I'm Nick. I'm an animatics editor for animated tv shows. I'm an aspiring AE for live-action scripted drama. Looking forward to taking my first steps!
