Not GP but everyone has different stories about American public school being awful. For instance my issues with school started with having to drop from pre-algebra to remedial arithmetic in 7th grade in order to start in the gifted classes in middle school. It was a bit of a Sophie’s choice because I really belonged in the advanced math track. The kids I was around in those remedial classes sucked and some of them would bully me for knowing things. So I learned to hide how smart I was. So it’s not going to be any one thing but rather a consequence of our culture of devaluing intelligence and learning coupled with how severely under-resourced our schools are.
