One thing to keep in mind in this kind of discussion is that the US is really big. It has 13,500 school districts. Its population is almost half that of all of Europe. Put another way, it has a population roughly the same size as Germany, France, the UK, Italy and Spain all put together. Among other factors that result from thus, there's a lot more variance in experience across US schools than there are in many European nations. In my experience at a (well-off) US public school, I had some teachers who were annoyed at my reading ahead/knowing things before they were taught, a select few who encouraged it, and a majority of teachers who mostly ignored me.
