Which is the best university the wolrd?

there is no such thing. that is like asking what is bhe best color in the world. everyone will have a differenct answer. harvard may be the best place for one student but horrible for another or not challenging enough do you mean the most prestigious? oxford. it is internationally what harvard and stanford is for america. all of the brightest in the world go to oxford. you must take sat, act, and an international test in order to gain admission. i was thinking about applying, but i didn't wanna take the international test cuz it was way hard!

I think it depends on what subject you are taking. For example, for engineering the best university would probably be Massachusetts Institute of Technology or Stanford. For law the best university may be Yale, Harvard or Oxford. ~Cellophane
