My D was assigned to take an online quiz with a deadline of 7 pm. She began taking it at 6 and was near completion at 6:45 when the program inexplicably logged her out. She was unable to log back on and contacted IT. They told her that they have been having a problem with it lately and to contact the Professor and explain what happened. The professor responded to her email that she couldn't help her out because my D had waited until the last minute to take the quiz and now it was too late. (My D emailed her at 6:50 immediately following her phone call to IT).
She emailed her again and received no response. This will bring her grade from an A to a B if the professor does not help her out with this.
