Lets say you got accepted into NYU's Stern business school (one of the best in the nation) and into Tulane's Freeman Undergrad Business School (nowhere near as good as Stern)
NYU's ranking is #32 while Tulane's is #52.
However, NYU offers you financial aid of $10k/year, so youll have $50k/year to pay, while Tulane offers you a full ride (AKA "Paul Tulane Award") for all 4 years?
Which would you go to? I would choose Tulane since that would mean no loans to pay off, and the school itself is pretty decent.
