Up until age 14 (or thereabouts, Year 9) us English are given the SAT's (different to the american test of the same name.
Many people in the US don't take the SAT untill 11th grade. You try to compare 14 year olds to 17/18 year olds. The only reason the US scores poorly is becuase the education system focues on college preperation, insted of workforce preperation.
Europe VS United states? u cant fight in this one... there are a lot more useless waste of life living in the US then europe
The US has 300 million people, the UK does not have that many. Yeah, if you have more people, you are going to have more bums.
