"新加坡国立大学（世界排名18）"

- - I guess this ranking does not include American universities.
The schoold I'm currently in has a history over a century, it's produced over a dozen Nobel Prize winners raning from chemistry to physics. But it was only ranked
between top 20 and top 30 within United States, so the ranking (espeically the so called international ranking is a piece of junk, no offence, it  merely
a game of politics) does not tell people much about how good the school is.

Based on my experience and observation, very few universities(best universities) in Asia can really compete with American universities in all aspects,
i.e, they might be ranked between 60 to 100.
