How Australian Universities Edge Out Ivy League

[LutherVan]

Numerous British Commonwealth institutions are clearly overrated by QS and THE, both of which are headquartered in London. I ignore their rankings.

ARWU (China) is considerably more reliable, and only one Australian institution makes their global top 50, the University of Melbourne which comes in at an underwhelming #44.

ARWU ranks 6 of the 8 Ivy League schools in the world top 17.

Please what makes ARWU “more reliable”?
