I would love to, but I have an exam tomorrow that I have only been to one class all year. I have to read Wikipedia all night

good luck..
I remember doing this at university as well. I did Physics but we could take a couple of courses from other depts and the 'Introduction to Business Studies' course got a reputation (quite rightly) as being a bit of a doddle. I went to the first couple of lectures but as they were at 9am that didn't last long. I figured there was enough information in the course sheets that were handed out to get through the exam, and most of it just seemed like common sense.
Come the day before the exam, I went to bed at 2pm (after being up all night), woke up at 1am, spent all night learning about Business Studies, toddled off for the exam at 9am and absolutely walked it.
The start of the exam had to be delayed for a while whilst they got more question sheets, as over twice as many people turned up as had been to the lectures - I obviously wasn't the only one.
