Forget about all these so-called "studies" - they are always rigged and controlled by political interests. Take the PISA study for example. There was a big discussion in Germany a few years back why the country ended up so low in the ranking, and that something had to be done. Turned out that it were only those German states that were ruled by the Social Democrats and the Greens which dragged Germany down. The state of Saxony, ruled by the conservatives at that time, was even ahead of Finland and would have taken the #1 spot if it would have been a sovereign country. Guess what happened after the Spiegel magazine published it: the politicians made sure that the statistics was only available for the whole country from then on and not on a per state basis anymore. Same happens everywhere; also in Poland. The f*ckers are just covering up that they are messing with the education system.
The US are way ahead from K to 5. After that they quickly fall behind.
...much further ahead of the American students
