I know that my experience is atypical but shows another example of resisting the cookie-cutter approach to the Public Indoctrination Center.
We lived in an unincorporated area a quarter mile from Seattle City Limits. Because of this my parents enrolled us into the neighboring suburban town's school system. It turned out that they were even worse than the big city propaganda mill. In my junior year of high school I was expelled from school for assaulting a teacher (he had it coming).
I ended up at Rainier Beach High, notorious for being invaded by armed Black Panthers. Rainier Beach was a community that had been solidly middle class for almost a century but in the last 20 years seen the ravages of urban flight. Pretty scummy.
Scholastically, RBH was about a year behind the school I was kicked out of - a fact that definitely worked in my favor. My classes were easy to ace (compared to the fellas around me who struggled to remember their names) and so I spent most of my time chasing girls. I had a car which was uncommon, for reasons probably related to the plummeting status of local residents. As such I could come & go as I pleased.
Drug use was exploding in the schools and RBH was no exception. Because I had come in the middle of the semester, had a car, and chose not to assimilate, rumors began to swirl that I was an undercover narc. I had a couple of interesting encounters over this and the wreckage I left behind did little to dispel the rumors. Needless to say, I had a rep and I exploited it as much as I could.
I didn't keep track of my absences. I didn't care. I had soured on education and no longer GAS whether I graduated or not. But the work was so easy that I was still able to get good grades. The teachers at RBH were so immersed in the racial thing (mostly forced bussing) that they had no time to bother with me as long as I didn't go out of my way to trouble them.
As I began the second semester of my senior year I had all the credits I needed to graduate except US History. So I had one class in the morning and then left for school - I was taking an Auto Mechanics class at a local community college. This was so unusual that the teachers and staff at RBH were so thrilled with my initiative that they greased the skids for me to do this.
I didn't even bother with graduation - they weren't my friends (except for a girl named Gina) and it wasn't my school. I got my diploma in the mail, along with my notice to report for pre-induction physical (but that's another story).
