我亂了....

Tell the truth, my image of those schools is mostly from their rankings. But rankings always change, and also differ from different evaluators. I always deny that it's the standard I use to choose schools; I always claim that I really research those schools by myself. However, when the ranking changes, I'm confused. The school I normally consider good, such as UT Austin, is ranked #36 US MBA program, even worse than BU. I'm totally confused!!! I consider BU a not rigorous school, where the curriculum is not solid enough. But now its ranking rises to #28, I don't know if I can still hold my thought... Or it's already changed.
