I attended an international school in Munich with a dynamic student body. American 'honour' students plucked from the state AND private schools in the US, found themselves failing courses in which they had never averaged lower than an A-. In addition the education at the international school was, on the whole, mediocre. I'm no genius and 12th grade was a bludge! Friends of mine from 'developing' countries snickered at the level of required maths and science.
A friend of mine was recently in LA and met a well educated high-school teacher, who ran into problems when he failed practically his entire class in English. He was packing his bags anyway.
Do the words regession and deterioration ring a bell! It's the most backward 'developed' nation I've ever heard of.

Grueße an euch alle!
