When she applies to Ohio State she should indicate “live on campus” which will increase the calculation of her “need” and if the resulting financial aid package in spring isn’t big enough she can decide to live at home then. She should also be sure to submit the supplemental essays/application for Morrill and Stamps. Be sure to follow up and apply for ‘special scholarships’ through Ohio State’s Scholarship Universe when that opens.
Since she is a Franklin Co/surrounding area student she should consider adding Notre Dame regardless of the net price calculator. There is a full ride set up by Glenna Joyce that makes awards to either Notre Dame or Ohio State for students in that geographic area.
