Applying to grad school can be expensive. What applications are free?

University of Minnesota was free in 2010

here, a thread from past years, there are some posts with name of the universities with no application fee. you should double check to make sure that they are still free.

Also, some say that they can waive the application fee in cases of financial hardship. Some waive it if you come to their open house.
