it's about learning some stuff that you're not really interested in, everyone can live with that; but one example (I don't want to spam the board
): we took our final exams at the uni, and a friend of mine was really well prepared, better than all of us, and he failed, and one year after that, he repeated the exam, with different professors but the same subjects etc, and got a very good mark. the profs of the first exam couldn't even tell him why he failed in the first one, and it's very often like that. they didn't like him, that was quite obvious, and the reason why he didn't pass. sorry, but sth like that is really crappy.
