The article used the Quacquarelli Symonds rankings of universities worldwide and mentioned that just three German universities were ranked in the top 100 (two in Munich at 61 and 62, and one in Heidelberg at 64). Well, I went to the source for comparison, and the rankings of these U.S. universities were similar: University of Texas at Austin, 65; University of Wisconsin at Madison, 56; Brown University, 57; Georgia Tech, 72 — none of which are tuition-free.
