Relax, it's just a quiz
Citations per faculty: 20%
International student ratio: 5%
A lot more people speak mandarin than french.. language is far from being the only determinant, but it does have an influence. Comparison of universities and the worth of their education are two different things, although some indicators are interesting.
Alternatively, feel free to tell me that the quiz already does accept "beijing," and I simply misspelled it like a dummy :)
Suggest therefore that many of the COLLEGES at Oxford and Cambridge would push many of the USA Universities down the list.
