As harsh as it was, I loosely agree with 'Getting Banned 2'.
In the sense that, no, what those kids are saying is utter BS. Hell I basically failed my A-levels (had to do an access course), and here I am, about to start my Master's with a solid 2:1 undergrad degree. Now by no means am I Einstein-smart, but I can certainly tell you I'm a far cry from 'dumb' too.
