I know exactly what you mean!
At uni, I have the two coolest friends, I love them, but they are SO lazy!
They both did Film Studies at A Level, so they know most of the basics, but I didn't so when I started I was a complete beginner, but they don't pay any attention in class, when we have worksheets to go through, they copy all my answers, because most of the time they haven't even bothered to pay attention to the film! But you can guarantee when it comes to the end of module essays, they'll do better than me because they have all my notes, and are better at writing essays than me. It's so frustrating! I could actually scream sometimes!
But the one good thing about it is that when it comes to the 'real world' they won't be able to bs their way through! Lazy people will never prosper.
I hope!
