I am registered for a maymester class that started today. The professor emailed us at 12AM to say they would upload the content at some point today, yet the day is nearly over and still nothing. On the schedule uploaded in the syllabus, there is apparently work due tommorow night. I emailed the professor, and I have gotten no response. I need to take this specific class, so I am hoping the class doesn't get cancelled or something. Is this unusal? Or has someone experienced something similar?
