For me the exams werent a problem, you just download the answers, set your computer to play the stupid animation for half an hour and go do something, return and take the test.
But the bitch of it is the game is pure, filtered, shit. Its nice to have a realistic game, but not to the point of boredom. I either end up playing so carefully so as not to die that it was no fun, or get a little sloppy and die and have to sit and stare at my corpse for the next 5 minutes. Yes, most servers I played on did not even enable the team follow camera after your dead....
