The other day, I was looking at the QS World University rankings. Since the university I plan to attend is ranked 481-490, I was browsing through that range, when to my astonishment I saw College of William & Mary in the 501-550 range. I'm not an American so I don't know that much about American universities, but I was under the impression that College of William & Mary was an excellent institute. I expected it to be at least somewhere in the top 200. Why is it ranked so low?
