Don't worry about it. I dossed at Uni, spent more time doing journalism and dj'ing than work and got a 2:2. I lied on my application (1st), nailed the interviews and now work for a big four. It was from Oxford, but all I needed to do was to get my friend who does graphic design to doctor a forgery when they actually asked for evidence. They didn't even check with my college or the university!! To be honest though I don't hold some of my (supposedly 1st class) contemporaries in high regard - strangely my irreverence seems to come off as 'banter' – which is highly amusing. But I beat the system, and am fairly capable. Since there's no solid foundation for morality anyway, just cheat. If you can justify it through situational ethics, that's all that matters. And you won't lose sleep.
