> Polish high school students indeed know more and are better at problem solving than most US high school students, * that said, there are high schools (public!) in the US that offer university-level courses and are excellent, * and university-level education seems to be much better in the US I'm curious how you compare students in different educational systems. Like what is "high school" and "university" in Poland. I ask, because every time I read something about the American education system I have quite some trouble assessing the statements because of the foreign categorizations. For example "school" in Germany comprises the first 12 or 13 years of education, with the first change of school happening after 4 or 6 years in primary school (with school starting at the age of 6). The following 13th till 18th year of education is held at a "university" where you earn a Bachelor and a Master degree. A PHD would be 3 to 5 further years in university. I've pieced together that the American Bachelor seems to be more broad than the German one. My Bachelor degree was in Mathematics and it did not contain some mandatory stuff in humanities for example. Yet it seems we learned that stuff in the first 12 (/13) years already and thus the German Bachelor starts later than the American one? But that would also mean that German students would spend more time overall in education (the current average (of people with higher education) might be about 18 years) and I also find that implausible. Basically I'm asking: Does someone know of a good comparative introduction to the American education system?
