A great complement to business school rankings is MBA Watch, which actually allows you to compare different rankings in one source. What’s more, MBA Watch aggregates information from multiple sources and from a population of users. Not all of the information is official, but it’s dynamic; you can compare your stats to those of other users of MBA Watch. There is also a lively discussion area in which you can interact with school representatives and alumni.
