Can you post the list? It's so lame that they make you create an account to see it.

The ranking of US universities within this list is quite different from the US News rankings. That suggests at least one of them is bogus.

Different survey uses different "filter".

Wow... not one mention of the Indian Institutes of Technology which may just be the toughest engineering schools on the planet. Just have a look at their entrance exams...

Bias anyone?

High entrance requirements are only one of the factors which define a good university. I'd say that the quality of teaching and the quality of research performed are more important than the quality of incoming students.

The IITs have a good undergraduate program, one of the best in the world. The graduate and research output of the IITs is nowhere as good. In fact , the research in particular is fairly mediocre, compared to say Stanford or MIT.

Couple things:

1) Considering there are over 1 billion people in India, IIT decided to "filter" students AFAIK

2) Scores are calculated by averaging all other departments, in which IIT might not even have or weak.

No they're not bias. If they are, then Waterloo University should be somewhere within top 10

I went to #70, Nottingham. At the time, it had a reputation for being insanely difficult to get in to study mathematics there, which is why I applied ;-)

Interesting to see Peking and Tsinghua at 36 and 40, respectively.
