In my case, I know it's not the registrar as I have personal confirmation from the registrar that she posts grades as they come in and they show up shortly thereafter. What pisses me off the most is that I work my ass off to study for an exam, put in hours upon hours of study time. You would think that the prof. could at least reciprocate a fraction of that effort take their lazy asses down to the scantron machine and retrieve the paper from the other side. Then, proceed to their office, formulate a curve (it must be hard to put those numbers in descending order) and turn in the sheet to the registrar within a 36 day period. I just don't think that's asking too much considering the effort I put into studying and the amount of money that goes from my pocket to theirs on an annual basis.
