Not really like my American Teen experience at all

Although im sure this film depicts the overall "usual" experience of high school in America, i cant relate to it that much..
I graduated the same year as the movie (2006) from a large (3,000 students)school in a very major East Coast city..
In my school, there were sort of cliques, but not really the same, anyone from one clique could be friends with someone from another. Although im pretty sure that this is due to the facts that the demographics of my school district is around 80%-85% Black, 10% White, and 5% Everything else, and from my experiences alot of inner-city schools are like mine. (Im white btw, and def not racist dont get that twisted, i associated mostly with non-whites up until college)..
But anyway the cliques basically were (in order of size):
1. "The Gangsta" kids, bringin guns and sellin drugs n *beep* at school, life goals included being the biggest Hustler and runnin the Block. Most do not graduate.
2. The in-between kids, most still do drugs and some illegal activities but they still get there school *beep* done as well. Most graduate, some go to college
2. The kids who actually make they're education their number one priority, most do not do drugs, they get good grades and strive for success, all graduate and go to college.
But i guess my point to this is that not all american schools are like the ones in this movie, as i kno alot of ppl from schools like mine. And just to point out that there is other systems out there in American Schools...
