Is it ethical to give a final exam after the professor has quit before teaching the remaining chapters of the course? I am enrolled in a lpn nursing program, and the professor teaching the pharmacology course announced to the class last week that he wont be here the following week, due to a "conference in California", and that another teacher would come and teach us the remaining chapters for the final exam.

Today no one showed up to teach the class, and the director is now claiming she had no idea he wasn't going to be here to finish the course. The director told us to read the rest of the chapters on our own before Wednesday (basically teach ourselves 6 chapters worth of pharmacology)... oh and there is also a HESI examination that they are saying we still have to take on Wednesday even though we haven't covered all of the material. I feel like the school is setting everyone up to fail at this point so we have to pay 3,000 to take the course again. I really need to know if this is ethical??
Remember Hanlon’s Razor: "Never attribute to malice that which is adequately explained by stupidity."

I doubt that any of the staff at the university are deliberately trying to make you fail so that they can make more money by forcing you to redo the course; it’s much more likely that someone just put things off, failed to read their emails, or something similar because they were busy with other things.

Complain to the student ombudsman at your university if you feel like a failure by the staff to properly follow procedures has disadvantaged you.
