Arnette, UNT has an honor code. It is agreed to every year by every student when they pay their tuition. It is also restated on every sylibus. I can almost bet it is at the bottom of your profs.
You should already have an appointment to discuss your grade. I think this is a perfect time to discuss the people not being honorable. If you don't want to be a tattletale, then don't mention names. You can get your point accross without mentioning names. If the prof believes you, as I think he will, then he might administer a pop test. This might be your saving grace, if that makes sense.
You studied hard and deserve to be rewarded for the time you put in. The other students shouldn't. And the fact that this is a senior level class only infuriates me. They should know better. They should care more. The should be more respectable and honorable. They aren't setting good examples for the type of people soon to graduate and be in America's work force. ARGH!
