You think everyone who got a 2:2 just drank in final year? Seriously? I didn't drink once in final year. My dissertation had to be restarted twice because after being given the go-ahead I was told it was far too broad, which meant it had to be started over. Within 6 weeks I wrote a 16,000 word dissertation which needed huge amount of primary research and five 6-7,000 word essays- 4 of which were due on the same day as another and all of which counted for either nothing but still had to be done (2) or the whole of the module. I was in the library from 9am-8pm every day, I frequently had to work on 48 hours of no sleep and I was sick from stress and overwork for much of that time. Everything was done on time with extensive research BUT it was not done to the best of my ability as I literally could not devote my all to each piece. So I got a 2:2 and was refused the chance to appeal it. I was the only person in my course who had all of those deadlines on top of each other and the only one with an incompetent dissertation tutor who set me back by weeks.
I understand that there are of course people who prefer to socialise rather than do their assignments properly, but to throw everyone who gets 2:2's and under into that pile? You are delusional.
