It makes a huge difference.
It seems (overwhelmingly?) common for ones high-school friends to be your classmates.
Highschool students are not randomly distributed to schools across America. There are schools that look like war zones, and places where kids actually learn. Moving the kids to different schools isn’t a solution because it’s the kids that are the problem.
EDIT: Many did take the exam 2 or 3 times, until they got a score they were satisfied with.
We still partied, drank, played a fuck ton of video games, generally did stupid shit, normal teenager things. This was largely the case in neighboring schools as well (the Atlanta northern sprawl is very large).
I'm not saying we didn't have parental involvement; we absolutely did. They had the resources and investment in our education to push us along that path. Our school also had a lot of resources. But it wasn't prison.
I'm not sure if it was the parental involvement and their expectations or the resources and quality of education at our affluent school. Most likely both. Whatever it is, I think it's a travesty that it isn't the norm everywhere to have an opportunity for that kind of education. There is so much wasted potential in this country.
My (public) high school class was commented on from grade school as being remarkably bright. But about 3/4 the bright kids were lazy as fuck and got terrible grades (myself included—and I don't mean the try-hard version of terrible grades like "oh no I got one b-", I mean Cs and Ds not being uncommon)—but then killed on standardized tests, 95+ percentile, very certainly not due to application of remarkable effort or even trying all that hard.
