I'm Irish so I haven't a clue

Is high school in America really how its made out to be in every film.

Where people are categorised in groups like the jocks, the bitches, the geeks etc.

Are there really the main girls that walk about thinking they own the place?

Are cheer leaders really assholes? That think there better than everyone.

And is prom really like the biggest deal ever?

Do people really think high school is the most important time of there life where everything they do will mean it all for the rest of thier lives?

And does that amount of bullying really happen?
