While MHC other schools promise to meet 100% demonstrated need no one promises that a student is not responsible for self help as part of their package. Many are very upfront that if you don’t meet your self help need that you will not get additional funding.
Remember some students are dependent on work study because their families can’t or won’t meet their EFC and want to use work study to fill that gap.
Brown used to provide additional funding freshman year so that students do not have to do work study. I do not think that is any longer the case.
